Summary: intel driver: messed up framebuffer shown before
redraws.
Product: openSUSE 11.1
Version: Beta 3
Platform: Other
OS/Version: Other
Status: NEW
Severity: Normal
Priority: P5 - None
Component: X.Org
AssignedTo: sndirsch@xxxxxxxxxx
ReportedBy: lverhaegen@xxxxxxxxxx
QAContact: xorg-maintainer-bugs@xxxxxxxxxxxxxxxxxxxxxx
CC: aj@xxxxxxxxxx
Found By: Development


In beta3, with the intel driver, running KDE, when some actions are undertaken,
the content of the framebuffer is completely messed up and displayed for a
brief time before the redraw happens. While this is no functional issue, it is
worrying for the user.

It looks very much like the issues we saw when not blanking the CRTC on
radeonhd during the first few months of radeonhd development. We saw the
scrambled FB content, with FB layout changing, before the FB was properly
filled again. And we then just had the CRTCs send out black instead and
everyone was happy.

AJ: can you give us some more information about the hardware, maybe attach an
Xorg.0.log?
