Comment # 12 on bug 69341 from darkbasic

I noticed something weird: if I start KDE with desktop effects off it is *much*
faster and there is corruption in the title bar. On the contrary if I start KDE
with desktop effects on and *then* I turn them off nothing changes: it keeps
being very slow and there are no signs of corruption in the title bar.

Also I noticed it is much faster when I set resolution to 1920x1200 compared to
2560x1600, at least when starting KDE with desktop effects off.
