Sorry that the develop panels go black while importing or exporting images in Lightroom Classic CC 7.4.
Could you please try importing images with the GPU disabled in Lightroom? Uncheck "use graphics processor" under Preferences> Performance menu in Lightroom. Refer the screenshot below for reference and this article for details: Adobe Lightroom GPU Troubleshooting and FAQ
Let us know how it goes.
thank you for your message
I did as you suggested; uncheckd « use graphic processor »
but the same happened again: black side panels when I supressed a folder containing +/- 50 pictures from Lightroom Library
No access to side panels, they get black
I have to quit and restart Lightrrom - and wait for it happen again after a while…
Is it due to my graphic processor?
This did not happen before updating Lightroom classic CC to last version a few days ago
Thanks for your ideas and help
Does pressing the "Tab" key switches the side panels back to its expected look?
Also, please check out the comments mentioned in this discussion as this problem used to be a bug in Lightroom 6/CC few version back but it has now been fixed: Lightroom 2015.7+: Panels and filmstrip black when switching to Develop | Photoshop Family Customer Community
pressing the « Tab » key removes the side panels, but when they get back they are black
changing from Develop to Library Grid by pressing B then G doesn’t help either
the only that helps is pressing the « Yellow button » (between red and green button in the upper right corner)
to put Lightroom in the dock it reappears ok, but it doesn’t last - the black panels do reappear quickly and I have to restart Lightroom
My computer expert told me to not to update EL CAPITAN 10.11.6 to High SIERRA because this causes trouble
actually I did upgrade to High SIERRA once and it made the whole system collapse….
I had to reinstall all programs from scratch
What do you suggest?
LR is tripping over a bug in Macos 10.11. The only reliable solution is to upgrade to 10.12 or 10.13 and upgrade to LR Classic (LR 7). See Adobe's official reply in the bug report: https://feedback.photoshop.com/photoshop_family/topics/lightroom-2015-7-in-macos-sierra-bu gs?topic-r...
