Hi, I have an annoying problem. When I hover with the mouse over a picture in develop mode the picture becomes slightly brighter. However, sometimes it gets darker. This also affects the background (grey in my case). Only restarting LrC helps.
Aynone knows what the problem is?
Please post your System Information as Lightroom Classic (LrC) reports it. In LrC click on Help, then System Info, then Copy. Past that information into a reply. Please present all information from first line down to and including Plug-in Info. Info after Plug-in info can be cut as that is just so much dead space to us non-Techs.

Try disabling GPU in preferences, any difference?
Thx for your answers, I appreaciate it. Indeed, disabling GPU acceleration seems to solve the issue (LrC-->preferences-->performance-->Use Graphics Processor "Off"). I'm using a MBP 2015 15" without dedicated graphics. So it might be the setting caused the problem then because there is no dedicated card to address?
If your MacBook Pro doens't have a dedicated video processor, then best you switch off GPU as it will reduce rather than improve performance.
Just to clarify: this bug occurs on Macbooks with dedicated graphics as well. I'm using a 16" 2019 model and I have the same issue like back then. The workaround it to switch off graphics processor for a second. You can switch it on immediately again if you like, it will work normally then.
Thanks very much for posting this. I started having this issue whilst using a second monitor with Lightroom Classic.
After extensive phone calls with NEC who made the monitor, Apple and Adobe - the issue was unresolved for a year.
Last night, found this post and it worked. Thanks so much!
By the way, you can turn it off and on again immediately, it will continue to work normally again until next time. For example after your computer comes back from sleep. But anyway, least annoying way is of course to leave the acceleration shut off.
