Hi @friedpan, and welcome!

I’m taking a guess from experience that that is because of the compositor, kwin crashing. Mine also did it, but stopped for some reason unknown to me.

However, I did have an workaround. To restart the compositor, simply run:

kwin_x11 --replace >/dev/null 2>&1 &

I did that whenever it happened. (Usually after resume from suspend.)


If you have the Desktop Effect: Slide Back activated, deactivate it.

Slide back is not enabled, can confirm that kwin_x11 --replace >/dev/null 2>&1 & resolves it once it actually happened, though.

yeah,it work for me ,everything began to be fast again
