KWIN_TRIPLE_BUFFER=1 kwin_x11 --replace &

fixes it. I guess it restarts the compositor and more. So the question is does
it stay fixed after that is run.

I created kwin_env.sh as described and rebooted. i still had the flickering. 

I did 'echo $KWIN_TRIPLE_BUFFER', to check if I had done everything correctly.
It did not return '1' , so perhaps I messed up, though i cannot see where.

I put all compositor settings back to defaults. i was about to write how the
problem had gone, then 10 min after login it came back. "SHIFT+Alt+F12 twice"
fixed it (temporarily, I guess). At least I have an efficient workaround.

I renamed this report.

[kde] [Bug 358963] New: "full screen repaint" not sticky with reboot

[cf via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=358963

Bug ID: 358963
   Summary: "full screen repaint" not sticky with reboot
   Product: kde
   Version: unspecified
  Platform: Kubuntu Packages
OS: Linux
Status: UNCONFIRMED
  Severity: normal
  Priority: NOR
 Component: general
  Assignee: unassigned-b...@kde.org
  Reporter: andybuc...@gmail.com

I have flickering windows. i find setting compositor to "full screen repaint"
fixes it. 

Flickering returns every reboot. I go back to compositor settings, choose 
something else, then go back to "full screen repaint" and it is OK again.

Reproducible: Always
