Since roughly March, I've had problems with text display not being updated until the main window is clicked with a mouse. Examples: Claws mail message list, deleting several messages leaves corruptions http://evolone.com/pics/screen-corruption.png gnome-terminal su login doesn't update with root prompt http://evolone.com/pics/screen-corruption-term.png At this point, I updated every library, but it seems an under-reported regression. I use gnome-shell, have for many months, no problems till recently. 00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03) (prog-if 00 [VGA controller]) Subsystem: Dell Device 0188 Flags: bus master, fast devsel, latency 0, IRQ 16 Memory at dff00000 (32-bit, non-prefetchable) [size=512K] I/O ports at ec38 [size=8] Memory at c0000000 (32-bit, prefetchable) [size=256M] Memory at dfec0000 (32-bit, non-prefetchable) [size=256K] Expansion ROM at <unassigned> [disabled] Capabilities: [d0] Power Management version 2 Kernel driver in use: i915 OpenGL renderer string: Mesa DRI Intel(R) 915GM x86/MMX/SSE2 OpenGL version string: 1.4 Mesa 7.11-devel (git-f274dfa) direct rendering: Yes i915 (Intel 915, 945) [1] classic * [2] gallium NOTE: Switching this to 'gallium' makes the text corruption go away, losing gnome-3 goodness.
Since you know approximately when it worked, can you bisect? Ken has also been running gnome3, so he might be able to bisect it too.

I don't "know" anyone here, so if Ken is watching, maybe he can reproduce the bug on his hardware too? Anyway, knowing nothing much about git bisecting I'm trying with little success. It would seem there are too many changes for my system to go back that far. I'd have to start with a re-installation... really not what I want to do. Anyway, I'll see if this one 3370f9b606217f53297d61b025a06f7bcf62648a builds and works, or if it fixes the bug. Rinse and repeat? I *think* the problem started for me when 7.10.1 hit me, up from 7.9.1, but I rebuilt other libraries, not suspecting a bug in mesa. Now, I can't seem to use my desktop when mesa is so old (without possibly rebuilding other libraries). Maybe somewhere in between I'll get lucky. IDK... seems really like a long-shot as I have to test this in a working desktop.

No change. Finally reverted git versions of gnome-shell, mutter, clutter, etc., to packaged releases. Problem went away. Sorry for the noise. I'll see if I can reproduce the problem via upgrades, and probably close this.

I thought the problem was disappeared, but it returned between 7.9.1 and updating to 7.9.2. I suppose I might try to find out exactly where, then.

Seeing redraw problems with 7.10.2, but not the same severity... My guess is there is a bug, just some combinations (of x server, WM) show it more than others. But, I can't reproduce the same bug anymore. Now I get, so far, only some artifacts in scrolling text -- this I can live with for now. Close this?
I'd say if your initial problem is gone, close it. Note that these sorts of failure-to-update-with-compositing-wm bugs are generally things that are bugs in the 2D driver (xf86-video-intel) and the server, as opposed to Mesa, so you might look there for where the regression was for your remaining issue.
Closing as that seems to be the general consensus.
