Exactly. And I've notived the performance of all the applications I am using
degrades at the same time. Restarting them or logging in/out is a big hassle
so I'm glad the enable/disable desktop effects works; otherwise I might've
moved away from KDE until a fix comes.
If people have ideas on how to try to track this down, I'd be more than happy
to try helping.
No ideas, but by running ksysguard I've noticed HUGE CPU usage when I
try to logout. I can't see what is
using the CPU, since everything visual freezes, but once ksysguard
"catches up" after I cancel, I have a big
hump. Same goes when just using alt-tab to switch windows. I can see all
kinds of activity, even though I'm
only seeing window outlines on the screen. No desktop effects active;
four cores; 6GB; no swap.
But I can confirm the workaround: Enabling and then disabling desktop
effects fixes the problem.
Do we need a new thread to call this to the right people's attention? Or
should a bug be filed somewhere?
