P: Panels and filmstrip black when switching to Develop

Does the UI element restore if you minimize the main Lightroom window and restore it again by clicking the Lightroom app icon on the launch bar?

⌘ Tab normally clears all panels and repeating restores them. I am seeing regular issues where the Side panels are not restored, leaving blank, black spaces on either side of the image.

Now I have a situation where the interface has simply frozen. Clicking thumbs produces no change, neither does hitting G / E keys in Library module. Second force quit of the day

I have been using the app all day and seen numerous minor interface issues.

Last week, before update, I ran a week-long LR workshop with zero issues.

MB Pro Retina / SSD / 16Gb RAM  MacOS 10.12.2

Same Here, I am unable to work!!!!!

Same here too. Intermittent but regular!

macOSX 10.12.1, LR CC2015.8 french language.
Même problème aléatoirement, il me semble que ce problème se produite si LR en fenêtre ne couvrant pas tout l'écran, laissé inactif plus de 15 minutes, lorsqu'on veux remttre LR en plein écran ou qu'on veut changer de module, par exemple en passant de Développement à Bobliothèque. Ce n'est pas systématique, mais ça c'est produit plusieurs fois.

Same problem randomly, it seems to me that this problem is produced if LR in window covering all the screen, left idle for more than 15 minutes, when we want to re-open LR full screen or you want to change the module, for example from library development.  It is not systematic, but it happened several times.

Victoria I may have to do that but the new update fixed a problem in Slideshow that I needed fixed. I'm stuck between a rock and a hard place.

I’ve been working in the print module and every time I hit the print button the whole background and side panels black out completely...the one workaround I have found is by minimizing the window and then bringing it back again. This started after I installed Lightroom 2015.8 on my 2015 iMac running OS 10.12.1.  The box Use Graphics Processor in the Lightroom Preferences is checked.  Unchecking the box does not seem to fix the problem.

The same issue

But before you do, if you are seeing this consistently, and if you are using GPU acceleration (Preferences>Performance>Use Graphics Processor), you might try disabling it and see if the problem resolves.  Just a hunch, but I don't ever experience this behavior on my MacBook Air, where I haven't enabled GPU acceleration, and I see it frequently but intermittently and unpredictably on my Mac Pro, where I do use the GPU.  My gut tells me there might be some sort of race condition developing between threads running on two different processors that are responsible for painting the screen.  (This is purely a WAG: I have no knowledge of Lightroom's internals.)

If you're seeing it frequently, it's very easy to roll back https://www.lightroomqueen.com/roll-b...
