Others indicate their crashes occur post-boot in compiz while switching desktops, minimizing windows, etc. but we don't have stack traces for these other cases so I can't be 100% certain. [Description] Since moving to mesa 8.x, we've had scattered reports where compiz crashes with stacktraces terminating in intel_miptree_release(). We thought updating to 8.0.1 would resolve these crashes (and perhaps they did; the frequency of reports seems lower than before). However we've still gotten a handful of people hitting it. I don't know what graphics these other folk were running; could well be Sandybridge. I have not been able to reproduce this on my own (non-Sandybridge, non- Ironlake) hardware.

The only requirement is to resize by a considerable amount, like doubling the size of the window. Small resizes work, though I get graphical artifacts in the resized area. I'm using a Sandybridge desktop (i5 2400) with a 1920x1080 single monitor. I can attach the crash file if necessary.

I turned on resize, resize info, and switched default resize mode to normal. I then alt-middle-click resized various windows from big to small and back. Tested on current 8.0 and master.

I've applied the patch atop 8.0.1 and posted the branch: git://people.freedesktop.org/~chadversary/mesa.git ; branch 8.0-bug-46739-log1 Could you reproduce the bug with this patch and report back with the log?
