Hi all,

I have the following problem: When I minimize a window, the desktop crashes - it becomes crumpled and starts flashing. Mostly this happens when I minimize a maximized window (e.g. firefox, krusader) however it happened several times also after minimizing an application from its "normal" size. The bug does not depend on whether any minimizing desktop effects are turned on or off.

Please can anybody help me to investigate why the above mentioned is happing.

I am using OpenSUSE 13.1, KDE 4.11.5, fglrx 13.251

Yes, it looks very similar.

I see this problem on my desktop running kubuntu 13.10 with AMD's catalyst 13.12 (13.251 packages). A workaround is to press ALT-SHIFT-F12 twice to toggle desktop effects first off and then back on. This usually fixes the glitch for the moment. It comes back when minimizing or maximizing certain windows.

can you elaborate on "certain"?
