https://bugs.freedesktop.org/show_bug.cgi?id=81644 --- Comment #21 from Aaron B --- I'm getting the glitch a lot more, but trying to remember what sets it off most: 1. Youtube. Often, but not as often as #2. 2. Clicking on an element that brings up another element onto the page, basically over it with a higher z-index, like I said facebook does this a LOT. 3. Adding elements to the page at all can also trigger this bug. Like loading ANY comments, from disqus to yahoo, they all have triggered it. 4. Slideshows where the objects slide against each other, like in PCWorld slideshows, just had a crash there. All of these have in common is moving pixels, but also adding pixels to the screen. Is there special code for that, those dirty rectangles being glitchy or something? I have, well, only bare minimal knowledge of how these drivers work from looking at lots of Git commits, but I bet that is a pretty good clue to people who know what they're looking at with what could be wrong. :) -- You are receiving this mail because: You are the assignee for the bug.
