Created attachment 502888 [details] required info After a recent upgrade, kde-plasma/plasma-meta-5.10.5 window started freezing sporadically. The only diagnostic message given was: QXcbWindow: Unhandled client message: '_NET_CURRENT_DESKTOP' Which seems to happen either when switching between browsers or multiple windows (I typically have 6 configured). This happens quite regularly (a couple of times a day). Sorry I cannot give any more info at this time. If I find more I will add to the bug.
The least info you could give is about `emerge --info` and your graphic drivers, how it freezes (fatally or temporarily).
I've already attached the required 'emerge --info' yesterday. Please see the first attachement. The freezing happens when I am working on researching some things on the net, or editing a document, and everything freezes. To gain some control I logged into a command line interface, started windows with startx, and then killed it when it froze by <ctr-alt-f1>, kill and restart it. I did find one possible clue though. When I rebuilt the the system 6 months ago it appears that I forgot to set the VIDEO_CARDS variable. As I recall I had set it some place as a radeon. The former one was set to "intel nouveau vesa". I will rebuild and test.
