Lightroom 2015.7+: Panels and filmstrip black when switching to Develop

Same here, I use Lightroom in the studio, editing 2k pictures a week. This is the busiest time of the year here. Adobe do something!!!

Also another strange behaviour but not as often.......sometimes when I go to a different folder in library module and than switch to develop, picture from the different folder (Last edited) appears on the screen...

Since the last CC update to LR 2015.8 I keep getting a random problem. All of a sudden the side panels and bottom row of images, plus top panel vanish. They don't hide, it's not a show and hide issue. They simply go black. 
Not sure if it's a random key press that I've been doing - but I'm pretty sure it's not. I've tried show and hide to get them back - but they aren't actually hidden. They are just blank. Only way to return them, is to restart LR. 

Screenshot attached. 

I have a colleague reporting exactly the same issue on his setup. 

I'm on an iMac 2015 5k retina. AMD Radeon R9 M395 2048 MB

I rolled back to 2015.7 and have had no problems

You can force the panels to come back on a Mac using Opt-Cmd 1 for the library, 2 for develop 3 for the map etc. Inconvenient, but Lightroom does continue to work normally. This happens when a lot of tasks are running at once. Unfortunately LR does not recover once the panels have diisappeared and you'll have to continue to use the Opt-Cmd keys to switch between modules.

After the latest update, I accidentally sometimes hit the wrong keystroke and suddenly only my image is showing and the rest of the screen is black. It becomes non-functional. Nothing will bring back the side, top, or bottom bars except restarting LR. What is happening? Another bug?

Hi Sara,

Bug is known and seems to have spread like wild fire recently. Many people complaining. Sometimes a simple click on a slider in the dev module makes the panels go black.
It's a real annoyance and Adobe is on the case

Is it too much to ask, as paying customers, for an official response as to when a fix is expected?
Without this information, it's difficult to consider whether it is worth risking a rollback to an earlier version.
I am disappointed that this issue made it past QC and am finding the wait for a fix rather excessive. Why, if we can't have a proper fix, has no hotfix been issued?

it still looks weird that they haven't come across this bug during their (supposedly heavy) testing

Developers are forgetting that sometimes less is more, that's why the OS was always better,more stable than the competitors....Apple is going in a bad direction, same with Adobe etc...

I am seeing the same thing in newest flavvor of OSX but it only occurs in CERTAIN folders when I CLICK on certain images that I KNOW are there. IF I minimize and then bring it back up the panels reappear but the moment I click on that particular image THEN it goes away again. Not sure if this will help the team working on the bug or not but had to let someone know what I found.

I've got the same problem.
macOS 10.12.2
LR CC 2015.8

I have the same problem. The bars appear again when I jump in and out of full screen mode (Green arrows on mac), but as soon as I click them the go black again..

Yesterday I contacted Adobe about this. Their answer: 'We found that this is the bug with this version of Lightroom . So please wait for the upcoming update for Lightroom . It will be fixed in upcoming update.'

Lightroom main window and panels, apart from lower browser went blank and unrecoverable. Had to force quit - not good. No memory shortages, 40GB installed sierra 10.12.2.
