Lightroom CC: Curves bug with Wacom Intous Pro

This thread has been going on since April when LR CC was released. Please read; https://forums.adobe.com/thread/1827333

So Adobe released Lightroom CC 2015.1.1 and new Wacom driver 6.3.13w3. In hopes of a remedy I thrashed Lightroom .plist preference files (keeping a backup) under my user account and did a fresh install of Wacom driver keeping nothing from previous version. Did that do any change? ... NO!

I'm getting seriously tired of this prolonged bug and it still affects; grabbing slider values and dragging (scrubbing ie. white balance), setting and dragging adjustment points on a RGB histogram, HSL picker tool and generally all sliders when scrubbing. As said before it needs a good push to activate any change, moving the pen fast and quite a bit of travel, then it jumps and moves alot. Thereafter it is somewhat smooth until you release the pen. Using mouse or tablet touch is as perfect as before, but I want to use the pen all the time. I belive that thelazydesigner is right about that this has something to do about Adobe programming a mouse slow down smoothing using LR to increase usability for accelerated mouses. But for pen and tablet usability this jerky and inresponsive feel is appalling.

Keep in mind after reading the forum thread that these issues only affect LR and not Camera Raw. Furthermore it is unaffected by turning on or off GPU acceleration. And sadly everything was working fine in LR 5.7.1.

Hi, I'm getting the same as Henrik- Windows 8.1, brand new Wacom Pro Small, latest driver (6.3.13w3) - with Windows Ink off, Lightroom CC 2015 sliders are smooth and responsive, but with no pen pressure.  Enabling Windows Ink gives the pen pressure but all sliders are sluggish.  You have to drag the slider, for a moment or two nothing happens, then the slider jumps too much.  Very frustrating, any help appreciated.

I just tested on Windows 8.1 with an Intuos 4 and the 6.3.13w3 driver. I don't see any difference in response on the Curves dialog regardless of the status of the Windows Ink check box.

There is a new procedure for trashing preferences files in Lightroom 6. You no longer delete the plist file. Instead. Close Lightroom. Hold down [Alt/Opt][Shift] and relaunch Lightroom. [Delete Preferences] Button.

It is also possible this is a Wacom Pro issue but I don't have one to test.

Ok Rikk,

thanks for replying. I trashed the LR preferences, but I'm afraid the sluggish responsiveness stays the same using a Wacom Pro tablet. As I mentioned in the Adobe Forum thread; it's using the pen that evokes these issues in comparison to tablet touch input or a regular mouse for that matter, which is as smooth as ever.

As for Wacom driver issues, I might prove you right as I've successfully rolled back the driver to 6.3.8-2 (in-stable for OS X 10.10) which removes the same sticky and sluggish feeling for all scrubby sliders including the HSL-picker tool. Although the curves bug remains. Now I'm back to stable 6.3.13w3 and poor performance under LR. Keep in mind that these issues only apply to LR CC and not Camera Raw even though they're built up the same. I have an Intel Iris GPU acceleration turned on, but that doesn't make a difference if I turn it off.

Let's hope for good Wacom drivers and LR upgrades once OS X El Capitan rolls out.

Same issue here, with Bamboo tablet. Doesn't seem to matter what kind of tablet it is, just the fact that it is a tablet. That's when the curves go erratic on adjustment.

Same issue here, I have had to revert to an older version of lightroom til this gets fixed. Can't use curves at all in the newer version!

Good for you, I was unable to revert to 5.7.1 as LR CC changed database structure of the Catalog (*.lrcat) file. Even though my most recent backup was once only a few hours behind, I stuck with it a while longer and by now it would be a tedious job to go over the last three months of work.

But hey, I like to try new things out and in the long run it's a good thing to implement GPU acceleration. It's just sad that this bug hasn't been squashed by now.

I'm having the same issue with my new 15" MacBook Pro and an 2009 MacPro. Curves is so important, but unusable at the moment. I Don't need new features but the basic tools should work.

These issues have been persistent for the last half year or so, and I'm glad to say that for my sake they are gone! I'm now running Mac OS X 10.11, LR CC 2015.2 and Wacom driver 6.3.14-1 .. FINALLY!

Sadly, not for me. I installed LR CC2015.2 and Wacom 6.3.14-1, but stayed on 10.10.5. Curves are still as jerky as before. Could it be that the new 10.11 is making the difference?

Is Windows Ink checked or unchecked in the Wacom driver?

I also tried it withe the latest Wacom driver 6.3.15-1. No luck. I don't understand why curves are working great in Photoshop and Camera Raw, but not in Lightroom.
I'm thinking about selling my wacom intous pro.

Hi, so I logged the 'laggy sliders' problem as a support call with Wacom. After a few email bounces back and forth (where they were telling me to turn windows ink off, and me pointing out this turns off pressure sensitivity within PS), they sent me the following.

** I've not tried this yet, so no idea if it works for laggy sliders in Lightroom, or indeed if it will fix the curves issue you are all describing, but I've posted here in the hope it will help someone **

------------------------
I asked you to test to disable the "Use Windows Ink". That was a test to narrow down the problem, not intended as a solution.

Try disabling the 'ripple effect' (Press and hold to right click) and the 'Pen Flicks':
Open the PEN AND TOUCH settings from the CONTROL PANEL.
Change to the PEN OPTIONS tab.

Select PRESS AND HOLD from the list of pen actions and click SETTINGS.

Uncheck ENABLE PRESS AND HOLD FOR RIGHT-CLICKING to remove the "ripple" effect.

Change to the FLICKS tab and uncheck the two checkboxes.

If that does not help, he should try reverting to WinTab. Windows Ink is supposed to provide better functionality, but many users do not notice any difference.

Reverting to WinTab:
From Photoshop CC 2014, the 'stylus' changed to use Microsoft's system APIs. With these APIs you need to have Windows Ink enabled. These APIs give better stroke results and improve the out-of-the-box experience using Windows tablet/convertible devices.

If you want to go back to the old WinTab implementation of previous versions do the following:

• Close Photoshop

• find Photoshop's Settings folder, normally in:

C:\Users\[USERNAME]\AppData\Roaming\Adobe\Adobe Photoshop CC 2015\Adobe Photoshop CC 2015 Settings

NB AppData is a hidden folder! If you can't see it, you need to change your view settings in Windows Explorer to show hidden files.

• create new text file in this folder (e.g. with notepad) and name it: PSUserConfig.txt

• Open this file and paste or write these two lines:

# Use WinTab

UseSystemStylus 0
• Save the file, and open Photoshop.

• If you later want to rever to Windows Ink / turn off the gestalt's functionality, if it doesn't contain any other commands delete the PSUSerConfig.txt file, rename it, or move it to a different folder. If it does, change the lines so they read:

# Use Windows native tablet support

UseSystemStylus 1 Photoshop CC 2015

More about this you can find here :

Hope this helps.

Markus,

Don't hold your breath, it didn't work for me...

Tried the first part, Switching Flicks and Press & Hold off - made no difference, even after a reboot.

Didn't try the second, as (unless I'm reading it wrong) it suggests turning Windows ink off, then using WinTab instead for PHOTOSHOP - they key here being Photoshop.
That means Windows Ink will be off for Lightroom, which means I don't get pressure sensitivity in Lightroom. Or I turn Windows Ink on for Lightroom only, meaning I get the original laggy sliders. So I can't see the point of that.

I'm now trying the dreaded latest update to Creative Cloud in the vain hope that will fix it, but having read the reviews of the latest CC update, it's probably just going to break my computer even further.

Do you remember the good old days when you just took photos, and edited them in Lightroom & Photoshop without any problems :-( Ah, them were the days :-)

I talked with my contact at Wacom, here's what he suggested:

Right now I am not seeing any noticeable lag on my systems.

Try this:

1. Back up your existing settings using the file utility (Applications – Wacom Tablet – Wacom Tablet Utility) (save the backup as a zip in case I need to get it to an engineer either at Adobe or Wacom)
2. Using the same utility remove the existing driver completely.
3. Download and install the latest driver that posted last Friday ( 6.3.14-1 Win/6.3.14-2 Mac)
4. Report back if the problem persists
5. Reapply the backed up settings and see if the problem comes back. This will tell us if the issue is the settings that is causing the problem.

@Jeffrey, followed all of the steps. Downloaded the latest driver for Mac which is 6.3.15-1 (found no 6.3.14-2). Nothing changed. Still jerky, laggy behavior in LR CC 2015.2.1 curves adjustments. With and without my settings reapplied. Don't know what else I could do. I would give OS X 10.11 a try, but I cannot 'cos some of my hard- and software is not yet fully supported.
Someone in the forums told me it's working with an old wacom driver, but I don't know the exact version number and where to get it.

Btw. I don't have the Windows Ink option in the driver under Grip Pen-Mapping, but there is an Ink Tab in the OS X system prefs, which is turned off. I think that is the same

I have the same issues with a Wacom mouse.  Just installed newest LR CC and updated Wacom driver on my Intuos 4.  Makes the new Lightroom pretty difficult to use.

FWIW, I've heard from a couple of people having trouble with the latest Wacom driver, which was fixed by rolling back a driver version. YMMV.

hmm, well, it might be worth a try, but i've read elsewhere that old drivers and new drivers seem to have the same issue.  Thank you .. I'll look into that.

I wrote this bug report over a year ago and sadly these issues still remain. OS X is now named mac OS 10.12 and the only compatible Wacom driver is 6.3.18-4 and their user forum is gone.

Adobe CC Lightroom is up to version 2015.7 but the RGB curves picker and HSL pickers suffer from jerky adjustment and interaction, as described previously. All other Adobe applications are not affected and fine. Let's hope Adobe acknowledge this and releases a totally reworked LR 2017 including better GPU acceleration as PS does.

MPBr (2012) Sierra - Lightroom CC2015.7 - Wacom 4 Small - Driver Version 6.3.18-4  
GPU - on: Unable to duplicate your reported issue
GPU - off: Unable to duplicate your reported issue

Siders in HSL/ Curves in RGB Point Curve mode work smoothly and expected.

Rikk, thanks for taking your time trying to duplicate this bug, but I can tell you it's very real to me, and a couple of others I guess. I even tried a clean install with a totally new Mac mini i7 (without any plist-files or tablet drivers) quite recently and now running practically the same setup you have. It seems far fetched; but the only real difference is that I'm running Swedish language localisation, which Wacom doesn't support, however things are fine in PS and Camera Raw. The mouse and finger touch functionality on the tablet has been accurate all along.

I know it is possible to temporarily switch language in LR, but I really don't want to start messing things up. I guess I'll give it a try with a test catalog real soon.

This reply was created from a merged topic originally titled Lightroom - Curves panel bug - mouse 'falling off' edge.

If a point is near the edge of the Tone Curve box, the mouse consistently 'falls off' the edge and the point disappears. Once I click on a point, I want to be able to move that point without having to keep an eye on the tone curve to make sure I'm staying within the box.

What do you know.. this bug that seems to have been haunting us for ages is squashed as of LR 2015.8 in conjunction with Wacom driver 6.3.19-10 running macOS 10.12.2 and using a Wacom Intous Pro (PTH-651). I just had to pull the curve a couple of extra time just to make sure, but it's all good. Thanks!
