Output of org.kde.KWin.supportInformation
SUMMARY
I believe that it is unnecessary to repaint the entire screen when updating an
application's display. If this is incorrect, I apologize for the added noise.
STEPS TO REPRODUCE
1. Enable paint effect
2. Launch konsole
3. type something
OBSERVED RESULT
After every character is drawn, a full display refresh can be observed in the
paint effect
EXPECTED RESULT
Only the konsole modified line should be repainted.
SOFTWARE/OS VERSIONS
