Window content painting is always under control of the application -
it doesn't make a difference whether compositing is enabled or not.

Whenever I cause a redraw of a KDE-5 application, I always see a lot
of cycles spent in software rendering/blending loops - even for
operations which can be easily done with OpenGL (blits with alpha).

The kde page "KDE Mailing Lists" only shows this list - and a separate
list for developers.
Is there a separate list for plasma questions?
Thank you in advance, Clemens
