I didn't try the stable driver from the repository (260.x) due to bug 648718. Some newly opened windows are randomly shown as blank black or white rectangles in KDE. In some cases the root plasma-desktop window may become black, so the user sees a black desktop with mouse cursor and (probably) a taskbar panel. Blank windows seem to react to user input (blindly right-clicking results in a correct context menu), but do not redraw. The bug shows up only with OpenGL effects turned on, anything goes normal after turning them off or switching rendering engine to XRender. The same software stack works just fine with GeForce 8400M GS (in a laptop). This bug may be a known problem with older NVIDIA cards on KDE, mentioned here: http://userbase.kde.org/GPU-Performance, under 'nvidia - black window problem' section. Reproducible: Always Steps to Reproduce: 1.Log into the system 2.Turn on OpenGL desktop effects if it's not already turned on 3.Try opening some windows Actual Results: Newly opened windows randomly appear as blank (black or white) rectangles with usual window decorations and do not redraw at all Expected Results: Windows are redrawn correctly Tried removing ~/.kde4 before starting KDE4 also, but it didn't help. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
