Launching Discord or Steam causes KDE to freeze

As the title says over the last few months I have been having increasingly problems with my KDE desktop freezing when I launch either discord or Steam. The whole desktop seems to lock up but the mounse pointer can still be moved and I can switch to different tty and do a

systemctl reboot

sometimes I can launch them and the desktop doesn't but I get a notification sayinmg that the desktop effects have restarted due to a graphics reset. Anybody else having this issue? I am using a Nvidia 1080 GTX card with propriatary driver.

Compositor?
Try SHIFT+Alt+F12 to toggle it off before running discord or steam.

Tried that and the desktop freezes when I turn it back on.

Yep, that seems to be the issue I am having. Haven't checked dmesg to see if I have that error.

Re: Launching Discord or Steam causes KDE to freeze

The test was basically whether it would happen also without the compositor, which does not seem to be the case.
Thus compositor related.
As a workaround you could probably setup a window rule that blocks compositing for certain windows (resp. there's also some kwin script that does similar)

Re: Launching Discord or Steam causes KDE to freeze

I tried using window rules but the compositor still manages to freeze before the rule has a chance to apply. As a workaround, I wrote this small toggle script that will quickly disable/enable the compositor when invoked:

#!/usr/bin/env bash
if $( qdbus org.kde.KWin /Compositor active ) = true; then
        qdbus org.kde.KWin /Compositor suspend
else
        qdbus org.kde.KWin /Compositor resume
fi
