Yes, I think I can -- because there's another anomaly that cropped up around the same time, but which I'd put out of mind, as it is just cosmetic. That was that window borders get drawn incorrectly sometimes: they are normally green for the focused window and blue for the unfocused ones, but I've been seeing some mixtures of green and blue. Also sometimes a piece of window border pops up where it doesn't belong at all, like in the middle of an xterm popup menu. I'm guessing that on rare occasion it gets misdrawn in a really bad place, and overwrites something important, leading to the GPU hangs. And yes, the blue window border color is 0x40a0c0. The GPU hangs are too rare to bisect, but the misdrawn borders are repeatable, so I can bisect that, and see where it leads. I also seem to remember that for a while, window borders were misdrawn even worse; now the only ones that are misdrawn are quite thin (just a single pixel), but for a while fat ones, too, were being misdrawn. Not for long, though. (I forget what got upgraded to half-fix that.)</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
