Broken window decorations after suspend

Support KDE Plasma

I can’t tell when this started to happen, but I’m sure the issue is older than month or two.

After wake up my suspended to RAM PC, window decorations became unresponseive. Hover effect over min/max/close buttons are not working and window titles are not updating. For example, when I switch tabs in Firefox, window title remains the same it was after waking up PC.

Restarting plasma does not fix the problem, but changing Window Decorations settings from current to some other theme does the work. I tried to set different window decorations theme before suspend (nordic, breeze, plastik), but the behaviour is the same.

Any suggestion or workaround? I’m using latest nvidia binary drivers.

Here’s my inxi:

Add export KWIN_TRIPLE_BUFFER=1 to ~/.profile file.
And if didn’t work try with kwin_x11 --replace or killall kwin_x11 && kwin_x11 --replace.

Setting tripple buffer does nothing at all (yes, I relogged before trying).

Restarting kwin_x11 actually works, but it needs to be executed with nohup as background process, otherwise when I close terminal window, all window borders and titles disappear beyond usability. I had to switch to tty to reboot.

So, the solution would be running this after resume from suspend:

$ nohup kwin_x11 --replace &

Now I need to find a way how to automatically execute it after resume.

Thanks for the help.
