I'm also experiencing this issue with kwin_x11 since 6.0.0, still present in
6.0.2.
This is probably related to screenlocker and nvidia gpu. As soon as the session
is locked (either with a shortcut Meta+L or due to inactivity), kwin_x11 cpu
usage jumps up to 60%-80% of one core. I have another laptop with exactly the
same software versions but an AMD gpu and the issue does not reproduce there.
I've tried different screenlocker configurations: clock visible on and off,
wallpaper image, plain color, slideshow, etc., and the problem persists with
any configuration, with just the laptop display and with one or two external
displays, even when the displays are turned off due to the energy savings
profile. I also tried disabling compositing (shit+alt+F12) before locking the
session but didn't have any effect.
I usually leave the laptop running overnight, and when I get back in the
morning the fans are spinning fast, after unlocking the session cpu usage goes
back to normal and fans get quiet again. I had to disable locking the screen
for this reason, and just leave dpms to turn off the monitors after some time
but with the session unlocked.
One thing I noticed is that is not possible to remove the focus from the
password textbox, could it be that the cursor blinking is causing some kind of
re-rendering even when the screen is blank and the displays are turned off?
