Bug ID: 90264 Summary: [Regression, bisected] Tooltip corruption in Chrome Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: normal Priority: medium Component: DRM/Radeon Assignee: dri-devel@lists.freedesktop.org Reporter: falaca@gmail.com CC: kenneth@whitecape.org
There is intermittent tooltip corruption in Chrome, after the following Mesa commit: http://cgit.freedesktop.org/mesa/mesa/commit/?id=95073a2dca03a48f4c77bc846a4...
In order to verify, I built mesa 10.6 master from git (w/ llvm 3.4.2, to stay consistent with my git bisect) with those lines commented, and the bug is no longer present.
The bug has been reported here, and affects both r600 and radeonsi users: https://code.google.com/p/chromium/issues/detail?id=442111
On that page, affected users are reporting a range of kernel versions (3.16+) and mesa versions (10.4+).
Another anecdote which may help narrow down the issue: Sometimes the tooltip shows partial contents from a previously-displayed tooltip. As can be seen from the following screenshot, the tooltip shows the last few characters of the #radeon channel topic, followed by a white space and then the alt text of another channel: https://www.dropbox.com/s/lsg0walzuvw12of/tooltip_corruption2.png?dl=0
Another user (see IRC log from screenshot above) mentioned that sometimes the tooltip even shows contents from another process.
