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.
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.
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?
