I am beginning to doubt that the bug is indeed in X, because I can not reproduce it in pure X (without KDE or any other DE and any window manager, starting it via xinit). The holes in application windows and various graphical elements can appear only after I launch manually 'plasma-desktop' (this loads desktop and panels, but still no window manager). This suggests the bug may be actually located in plasma. Is it reproducible using the Clemens' testcase in something else than KDE (e.g. gnome)?
