Hello team / Christopher, One more interesting finding, which points towards Compiz + GLX + nouveau:
1. The glxgears works fine on first monitor (60 fps or more) but very slow on secondary. Actually, the speed is "obvious": exactly 1 fps ! This happens only if the whole window is on the secondary. If even a tiny fraction of the window remains on first monitor (even just a single pixel), the speed is normal. 2. When glxgears or glxheads runs on first monitor, the mouse-dissappearing-zone is clear and stable: No mouse pointer between 1/8 and 3/8 of the screen from top. This happens regardless of where the glxgear windows is placed (in 1st monitor). It also happens if only a tiny fraction of the window remains on first monitor (even just a single pixel), while the rest is in secondary. 3. When glxgears or glxheads runs on second monitor, the pointer flickers in the mouse-dissappearing-zone, however, it remains mainly visible. I found some older chats blaming the nouveau drivers for X-org. However, the nvidia does not work for me (no second monitor at all), so could not check.
