Version: (using KDE 4.3.2) Compiler: gcc 4.4 OS: Linux Installed from: Mandriva RPMs When opening menu or drop down list in Gtk (or maybe non-Qt) application switched to full screen mode, then window become black for short time. If then disabling OpenGL compositing using keyboard shortcut, then re-enabling causes that entire screen become black with only mouse pointer visible, and even without compositing Plasma behaves strangely - always visible panels disappears, but still are clickable, or sometimes are shown if other auto-hidden panel is shown. Mandriva 10, KDE 4.3.2, Qt 4.6 (from Cooker), NVidia FX5200.
