Photoshop: Lasso Tool line disappears after a few seconds of holding the 'alt' key down (win 10)

I agree it is not a good workaround. Engineering is currently looking into the issue. We appreciate all the details and movie you have provided to us which led us to reproduce the case.

This should now be fixed in the Photoshop 20.0.3 release.
Feel free to update Photoshop and let us know if this is resolved for you.

To update Photoshop CC to 20.0.3, click "Update" in the Creative Cloud desktop app next to Photoshop CC.

Thank you for the report Richard!

Hi Richard,
Have you tried updating graphic card driver? Also make sure to update Wacom tablet driver if you use one. Does it happen when you turn off "Use Graphics Processor" in Preferences > Performance? It requires reopening the document to become effective.

Hi. Thanks for the reply. These are brand new PCs, freshly installed. The cards are GTX 1080Ti. I disabled use gfx processer and restarted. Same problem.
Have you had a go yourself?

Another bug I have found is in the 3d filter to create a normal map: the various sliders etc don't update. You need to change from sphere to cube and back again to see updates. this is unworkable.

Do Adobe actually test these updates before shipping? We pay a lot of money for this.

I have tried on my end but have not been able to reproduce so far.
Did you already try turning on "Legacy Compositing" in Preferences > Performance panel (requires reopening the document)? 

Legacy mode seems to help the normal map creation. It has no effect on the lasso problem.

Thank you for the videos! I still cannot reproduce the problem.

You mentioned it happens both with CC2018 and CC2019.

Have you already tried these?:

Does your keyboard have 2 Alt keys? Could you also try the other Alt key?

It certainly happened with both 2018 and 2019, but apparently only on a W10 machine. W7 seemed to be fine. We can't be absolutely sure of this though and tricky to test now that we have rolled out W10.
Photoshop has literally only been installed for about 4 or 5 days on these machines as they are brand new. However, I was experiencing it on my previous W10 machine (a dual Xeon 64GB machine) that I have upgraded from. Weird that we have 3 artists here on three brand new machines running W10 (two of the machines are Threadripper CPU based with 1080Ti cards, and the other is a high end intel 10 core machine with a 1070Ti card. All have 64 GB memory).
KB does have two alt buttons, but I just tried using the other one and we have the same issue. Are you a member of Adobe staff Yuko?

Hi Richard, 
I can reproduce the problem now. Since you said it's happening in Windows 10 only and not in Windows 7 on the same machine, I was suspecting Windows 10 keyboard settings. Turning on Control Settings > Keyboard > Use Filter Keys > "Ignore brief or repeated keystrokes and change keyboard repeat rates" solved the problem for me. Could you try? I reported the 3D issue to engineers. 

Is this what you mean? I set the repeat rate down to slow (as per graphic) and it seems to be better. Still not perfect, but it takes longer before the lasso line starts to disappear. 

Go to Windows Menu > Settings > Ease of Access > Keyboard > Use Filter Keys. Then turn on "Ignore brief or repeated keystrokes and change keyboard repeat rates". Sorry, I omitted the "Ease of Access" in the previous reply! Hope below screenshot helps. 

Whilst this is a fix, it means that when writing an email (for example) you can't hold your finger on the delete key to delete characters etc. 

Please update to 20.0.2 and let me know if this update fixes your issue. Thanks!

This broke mine... now my sliders on the normal map filter has no effect on the preview...
