Created attachment 106387 [details] kwin_x11 --replace with trying to drag and resize via meta-mouse-left/right For a "long" time (currently uptime 50 days) everything works normal. But then, without doing anything special, things don't work anymore. I can't drag or resize windows or alt-tab between windows. Restarting kwin_x11 I can drag and resize, but when I alt-tab, it doesn't work again. Also when this happens, on konsole selected things or ctrl-shift-c aren't copied anymore. Problem also happens at three co-worker-pcs with similar setup. Happened by them month ago but I couldn't find out why. Neither of us did anything special. Updating to newer packages as they came didn't solve it. One with nVidia, 3 with Intel gpus. All Intel CPUs. All Debian testing. But not all on latest packages (currently 5.8.4, 5.8.5, 5.8.6).
Fix will be in 5.8.7 *** This bug has been marked as a duplicate of bug 377901 ***
Awesome. Thanks!
