SUMMARY Occasionally, various windows on my desktop appear completely black after opening for the first time. This happens to context menus (see attached screenshot), a Thumbnail grid task switcher, File Save dialogs or even newly opened applications such as Gwenview. Unfortunately, I cannot reliably reproduce this behavior, it happens roughly once a week and is fixed by a reboot. Most likely, this is connected to NVIDIA platform. I'm using the latest driver (535.54.03), though this bug was present with the previous driver version (525) too. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.27.6 KDE Frameworks Version: 5.107.0 Qt Version: 5.15.10 Graphics Platform: X11
