Public bug reported:
When I run sauerbraten in fullscreen mode in Ubuntu 18.10, there are
"skips" in the animation of the rotating cubes. Upon further
"evaluation", I noticed the system mouse pointer "popping up" briefly at
the moment of the glitch(near the crosshair) about once a second. When
not in fullscreen, the animation is smooth(no visible skips/glitches)
and I don't see the system mouse pointer "popping up" every second. It
works fine in fullscreen mode in Ubuntu 18.04.
To recreate/observe the problem:
0. Boot into Ubuntu 18.10
1. Install sauerbraten
2. Start sauerbraten
3. Set sauerbraten to fullscreen
mode(sauerbraten->options..->display->fullscreen)
4. Start a game(I like sauerbraten->bot match->start match->ctf->europium)
5. Move forward with the 'w' key(steer with the mouse) to some rotating
cubes. Here you should notice the glitch in rotation and the _system_ mouse
pointer flickering in and out near the crosshair at a rate of about once a
second.
