Same here. This does not happen every start though but >90% of the time. This happens with raster and native (both with OpenGL). Slightly resizing the widget and it is absolutely back to normal.

Details: KDE 4.9.2, Qt 4.8.3, gcc 4.7.2, Gentoo x86_64

I should add: Oxyglass style.

Confirmed by duplicates.

Comment 6 Matthias Dahl 2013-01-15 16:11:46 UTC

This is still very much a problem w/ KDE 4.9.97 and seems to be even more pronounced: The virtual desktop displays are diagonally offset by approx. 1/3 out of the total widget space until the widget is resized.

A clue: If most of the kdelibs and all of Qt is compiled as debug version, this does not happen (at least not in KDE 4.9.x). As soon as you switch to release builds, weirdness ensues again. :( Since Qt does several more sanity checks in its debug build, this is either a race-condition or something that gets fixed by accident (through some debug conditional logic) in the debug build.

Comment 7 Matthias Dahl 2013-01-15 16:12:35 UTC

Forgot to add: With KDE 4.9.97 this most definitely happens with every start.

Comment 8 Matthias Dahl 2013-01-17 19:14:41 UTC

With today's 4.10 branch, the problem is fixed. I was unable to reproduce this anymore. After further investigation: This bug seems to be a duplicate of bug#306414  which was fixed very recently.
