Jian, is rotation a required step to reproduce this bug? If so, this may be related to bug#20265.
(In reply to comment #3) > Jian, is rotation a required step to reproduce this bug? If so, this may be > related to bug#20265. Yes, it's a required step. But Jesse's patch to #20265 have no effect to this bug.
Does this happen if rotating after gnome-session (i.e. move step 4 before step 2)? If so, I'll consider this as major bug.
(In reply to comment #5) > Does this happen if rotating after gnome-session (i.e. move step 4 before step > 2)? If so, I'll consider this as major bug. If I start gnome-session directly, and rotating in gnome, it will have a disordered display. But when rotate it back to normal, it displays well.
How about using KMS?
With KMS, it will crash X with the newest code. As #20943.
This should be fixed now?
With the newest code, both in UMS and KMS, it works well if I rotate after I started gnome-session, but it will still has the blurred screen if I rotate it and then start gnome-session.

Yeah I see this too; but only after rotating then rotating back to normal and starting the session, both with and without tiling.
Even happens with EXA...
Happens on 965 too.
Ah no I see it with EXA but only if my pixmap management patch is applied, which points to the prepare/finish access hooks...
Seems like some sort of reuse or stale pointer issue. I can reliably reproduce this but only if no other windows pop up before I start the GNOME session. I had a failure dialog pop up last time, and when I started gnome-session after that it worked fine.
This commit may affect weird tiling issues: commit 87332a7cc16af82aa47e07fbf90da3635b071dbf Author: Keith Packard <keithp@keithp.com> Date: Mon May 11 13:52:00 2009 -0700 Use drm_intel_bo_disable_reuse API to flag scanout and cursor buffers (only kms though, probably)
I had the same problem with 2.7.1 when i just updated to karmic (ubuntu pre-alpha). I found this bug, updated to git and now rotation seems to work fine again. Im using a gma945 and exa (defaults to it).
Jian, retest please.
(In reply to comment #18) > Jian, retest please. It still has such problem with the newest code.
increasing priority, assuming users setting rotation in xorg.conf will be impacted.
I see this even with tiling disabled, can you confirm?
(In reply to comment #21) > I see this even with tiling disabled, can you confirm? Yes, with either server-1.6-branch and mesa_7_5_branch or all in master branch, with tiling disabled it still existed.
Created attachment 27343 [details] [review] clear bo of scratch pixmap to handle reuse Can you confirm that this fixes things for you in both KMS and UMS mode? It works for me, but I'm afraid it's papering over a bigger problem with scratch pixmaps. Keith?
