SUMMARY My screen will occassionally black out for a second or so while I am doing nothing but simply reading Reddit on Firefox. Sometimes it will flash for a second time just a few seconds later. It almost seems like something is crashing and restarting, so I've made my best guess and assigned it to the generic-crash component. Some details on my setup - running Arch Linux updated just a few days ago - Ryzen 1700 on an X370 Taichi with 16G of RAM - ROG-STRIX-RX560 RX 560 Graphic Card with AMDGPU drivers - using X11 with KWin's OpenGL 3.1 rendering backend - using Redshit and Plasma applet, but have had the screen flash on me whether it is enabled or disabled - screensaver is disabled - kernel 4.19.11-arch1-1-ARCH I see these errors from journalctl Dec 27 08:17:26 ryzen plasmashell[955]: file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:342: Unable to assign [undefined] to int Dec 27 08:17:26 ryzen plasmashell[955]: file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:342: Unable to assign [undefined] to int Dec 27 08:17:26 ryzen plasmashell[955]: file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:366: Unable to assign [undefined] to QString Dec 27 08:17:27 ryzen plasmashell[955]: qt.qpa.xcb: QXcbConnection: XCB error: 2 (BadValue), sequence: 14043, resource id: 52428817, major code: 142 (Unknown), minor code: 3 Dec 27 08:17:27 ryzen plasmashell[955]: qt.qpa.xcb: QXcbConnection: XCB error: 2 (BadValue), sequence: 14046, resource id: 56623111, major code: 142 (Unknown), minor code: 3 STEPS TO REPRODUCE 1.

Does the complete screen go black, or only the desktop and panels?
The entire screen goes completely blank. Thanks for asking. Any ideas?
That could be a cable problem.
(In reply to Christoph Feck from comment #4) > That could be a cable problem. Definitely not a cable problem. The time the screen is black is always the same (somewhere around a second or two), indicative of something crashing and restarting. The monitor OSD shows no indication that the hardware has lost its connection. Never happens in Windows. And I can't see getting the errors I'm getting if it was the cable.
If the complete screen is black, i.e. no windows are visible, it is not a plasmashell crash. It could either be a kwin crash (I am not sure if kwin restarts after a crash), or an issue in the video driver. Please add the output of qdbus org.kde.KWin /KWin supportInformation before (i.e. after a fresh boot) and after kwin restarts itself after such a black screen.
If KWin would crash the result isn't a blank screen, but windows being uncomposited and not decorated. I rather doubt this is KWin related.
> It could either be a kwin crash If kwin indeed crashes, then it would be great to have a backtrace.

You have to run `qdbus org.kde.KWin /KWin supportInformation`, though I doubt it would contain any useful information 'cause it doesn't look like a KWin issue. It might be worth to file a bug report against your video driver.
Vlad. Thanks for pointing out my error. I will rerun the command properly next time I see the problem. It doesn't happen that often.

It would be great to have dmesg output when the screen goes dark again. In either case, can you file a bug report against your video driver? This is most likely either a hardware or a driver issue.
