 Replying to [comment:2 Crissy]:
 > These glitches was not visible if hardware acceleration disabled, but
 without acceleration the performance is very bad.
 > First time I have glitches after updating Tor Browser based on Firefox
 52.x to 60.x.
 > The re-installation solved this problem.
 > Second - today. Also disabled acceleration helped. Looks like any
 library for hardware acceleration not changed or wrongly configured after
 update process. I enabled hardware acceleration, deleted Tor and
 TorBrowser and then installed TorBrowser. It helped. But it means: update
 process is defective.

 Thanks, that's really helpful. Is that issue reproducible on your system
 if you use an older Tor Browser, say 8.0.4, and update it? (see:
 https://archive.torproject.org/tor-package-archive/torbrowser/8.0.4/ for
 bundles) If so, how? Do you just need to update or do you need to have
 tabs open and update? Or...?
