Review request for kwin and Plasma.


Repository: kde-workspace


Description
-------

Fix flickering of sliding popups while disappearing

The last frame was fully painted for Plasma 2 panel popups, as it's
repainted in full on the last frame (without opacity and position
transformations applied).

Removing the repaint on this last frame makes the popups disappear
smoothly for me, without other side-effects such as artifacts on the
screen or other repaint problems.

Testing
-------

Ran kwin with this on Intel driver, flickering is gone in Plasma 2 and Yakuake 4.x.


Thanks,
