[Cin] AppImage and libGL errors at CinGG startup

 Noveau are very limiting and problematic (through no fault of those
who make them, who do a very good job).
If you have a fairly recent Nvidia you can try using the official open
drivers: nvidia-open.
With these drivers Nvidia equalizes with AMD. However, don't think
they are completely open: just like AMD, they have brought the parts
they want to keep closed into the firmware and leave only the open
parts in the driver.
