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.

Status in xorg package in Ubuntu: Incomplete Bug description: It seems to be duplicate of both : https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1641467 and https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1629300 . Possibly related to https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1278223 A - flickering in first display. The zone starts just below the top panel and its height is about 1/7 of the screen. Flickering starts immediately entering the zone, even half of the pointer may be flickering. To the centre of the zone, flickering is more prevalent, up to completely disappearing. The flickering has a periodic pattern, which seems to be affected by the windows displaying in the second (external) monitor !! B - external monitor. Some applications show really slow there. Worse case is HipChat (Atlassian chat program), which shows fine as long as even a tiny fraction exists on the primary display. At the moment the whole window passes to the secondary, then even the scroll bar has a delay of a second a move. To check, I have played with the ~/.config/monitors.xml without success. It seems that each configuration is saved there, even duplicates, after adding the same external monitor and re-configuring it (absolute duplicate in monitors.xml) C. Side-effects and related phenomena. Some times the "Screen display" control freaks, when enabling the external monitor. It may freeze or insist to put them in mirroring. Most of the times it just forgets a setup (although in monitors.xml) after adding a different external monitor. For each workspace, there is a different background, done with Unit5y Tweak Tool. All updates have been done, without effect.
