switching to Develop module with GPU support on blacks out my image:
when restarting Lightroom the first switch to develop module works correctly, switching back to the library module and the again to develop another picture leads to this black image phenomenon
The bug (black image) does not occur when starting LR, switching the ONCE to the development module and then moving between images (using the filmstrip).
It only occurs when switching back to the library module selecting another image and switching to the development module with this new image!!
As I wrote the bug occurs also when Develop.PreferOpenGL = true.
It occurs also when using the newest video driver.
It didn't occur in LR CC 7.12.
The second screen still shows the image.
Another detail for you Adobe guys to solve the problem:
When you start LR CCC with GPU support enabled and with a picture in development mode you can move between the images using the filmstrip without any Problem AS LONG AS YOU STAY IN DEVELOPMENT MODE. When you switch to library mode everything works fine. But switching back to development mode you have to select a picture which was already opened in development mode before (e.g. those which was selected when you switched to library mode).
Otherwise (when you Switch to development mode having selected a "new" Picture) this black Screen issue occurs.
So it seems to be a bug in a part of your code which is executed to load the picture into memory when switching from library to development mode.
What a joke ... I hope that Adobe will solve this problem asap
Since switching to Classic CC I am getting a black screen when move from Library to Develop. The R/A and Y/Y options display properly, and when I close LR in the develop mode, the photo shows correctly when I re-open the program.
Switch to Develop mode (the histogram responds to changes):
Switch to Y/Y in develop mode:
I am using Windows 7 Professional 64.
I have un-installed and re-installed with re-set preferences.
It's really strange that the picture is displayed properly in devekop mode when switching to Y/Y options but in normal display mode we only get a black screen.
Please fix this bug to reenable the GPU enable option!
Enabling GPU acceleration in Lightroom Classic CC causes the entire photo in be black in the develop module.
Closing and restarting Lightroom will fix the issue, but it returns if I go into the LIbrary module, and then select a different photo to develop.
Disabling GPU acceleration is the only way to definitively fix the issue. I am working with 46 MP files on a 2560 x 1440 monitor, disabling the GPU is unacceptably slow.
I reinstalled Lightroom CC (2015) and it does not have this issue, I can use GPU acceleration without a problem.
I bought a new video card (Radeon RX 580) and updated with the latest drivers in an attempt to fix this issue.
Interestingly enough, if I use the crop tool inside develop mode, the photo renders perfectly fine.
Seems that in development module it now wirks fine when you switch between images INSIDE a collection. (this also didn't work with LR 7.1)
But when you switch to another collection/folder the black screen phenomenon still appears! :(
I'm somehow tired of replies like "The black screen issue is most likely due to some driver compatibility or bugs. Do a complete clean install the latest GPU driver."Using a 4k display the GPU support is highly necessary for speed reasons and the exact issue description and observations in this thread make it - in my eyes - evident that there is a bug in Lightroom which causes this behavior.
