Original report and attachments were added by Mark here:
Short description (full history can be found also there, in original ticket):
When I run supertuxcart on skl, I see lots of flickering. See attached video. Curiously, I had to take a video of it with my phone, because the flickering *stops* when I enable gnome's screen recording (ctrl-alt-shift-r).
The non-flickering video is also attached for reference.
Danylo's patch has no affect on this behavior.
