Created attachment 109007 [details] Here is an example of what occurs after shading a window and moving it around on the screen. This issue only occurs when compositor on startup is enabled and only with the NVIDIA binary driver. The Nouveau driver does not cause the issue. The version of the NVIDIA driver used is 387.22. "Compositor Settings for Desktop Effects" settings are: Scale method: accurate Rendering backend: OpenGL 3.1 Tearing prevention "vsync": Never Keep window thumbnails: Never Checked "Allow applications to block compositing" Desktop Behavior->"Desktop Effects" are default. Team Fortress 2 & Ioquake3 trigger a bug in KDE when the compositor is on with the NVIDIA binary blob. After exiting the game the screen goes completely black. Moving the mouse cursor can make parts of windows or the panel appear. An open window acts like a big eraser removing the black color around it. If I shade the window my screen goes mostly black again except for the title bar of the window. If I open a new window portions of the screen go dark again. If I logout and log back in the issue is fixed.
It happens after the computer awakens from Suspend. I have to logout and back in to get the screen to stop turning black.
Probably not much we can do about it. The NVIDIA driver is proprietary, this makes it impossible to investigate such issues.

I wanted to report that I didn't have issues with KDE 4.14.3 with the same NVIDIA driver for what its worth. Thanks for the reply!
This issue report is quite old. Can you please confirm, that it still persists with KDE 5.23?
