Description Maciej Piechotka 2010-03-23 18:34:40 UTC
Intel driver from git makes (with mutter) screen blink as the various windows appear and disappear very fast.

There is nothing in logs.

xorg-server: from git
kernel: 2.6.33

please include full X log and dmesg anyway.  Also, you say it's a
regression, but don't say anything about what the working version was.

I'll add logs later. But working is 2.10.0,

In addition, please tell us the non-working version more precisely than
"from git". Things change quickly, and after just a few days it can be
hard to guess what "from git" might have meant. So a git commit ID for
the non-working version would be great.

Can you leave all other components the same and cause the bug by switching
only the driver? If so, then we've got a nice opportunity to bisect this
one and find the buggy commit.

6ea8ce640fbc7e5054b521a6f70b303945d0e849 + patch from bug #27922 ( attachment #35273 [details] ) + 2.6.33 - blinking
6ea8ce640fbc7e5054b521a6f70b303945d0e849 + patch from bug #27922 ( attachment #35273 [details] ) + 2.6.32 - works ok

Seems as if problem is with 2.6.32->2.6.33 (last stable displays ok on both).
