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 at lists.freedesktop.org
Reporter: falaca at gmail.com
CC: kenneth at whitecape.org
There is intermittent tooltip corruption in Chrome, after the following Mesa
commit:
http://cgit.freedesktop.org/mesa/mesa/commit/?id=95073a2dca03a48f4c77bc846a4a6d1f0eb81ae6
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.
