           Summary: Strange painting artifacts in applications

I suffer of strange painting artifacts on opened windows of several
applications (see the screenshot). Most frequently it appears when switching to
window using Alt+Tab. Seems that some areas of window aren't redrawn. If to
scroll down and then up, everything become ok. Looks VERY similar to bug
#187356 (please duplicate it if it's so). But in my case Xserver version is
1.7.x (I've tried 1.7.1 to 1.7.5, no changes) and Qt 4.6.2.
