Comment (by cypherpunks): Replying to [comment:3 gk]: > I guess this is on a Windows OS? Which version? Do you see error output or something on the browser console (Ctrl + Shift + J) while scrolling? Sorry for not mentioning the platform. The issue occurs on a Debian testing box. There was nothing in the browser console besides unrelated messages. I've done some more testing to try and find why there was a difference between Firefox and TB. Unfortunately the previous comparison wasn't accurate as the Firefox instance i used was heavily modified. Using a clean profile made the issue appear with Firefox too so it's not TB specific. Turns out issue is solved by setting `gfx.xrender.enabled` to `false`. Because I'm unfamiliar with the Firefox code base, i don't know what the preference does, what its impact is, and whether it's worth setting in TB. Hopefully someone else can figure this out. -- Ticket URL: <https://trac.torproject.org/projects/tor/ticket/19276#comment:4> Tor Bug Tracker & Wiki <https://trac.torproject.org/> The Tor Project: anonymity online _______________________________________________ tor-bugs mailing list tor-bugs@lists.torproject.org https://lists.torproject.org/cgi-bin/mailman/listinfo/tor-bugs
