This is most noticeable when you're trying to use Compiz and a dual-head
screen, where the desktop size exceeds 2048 pixels in at least one
direction. The desktop window exceeds the Mesa texture limit and fails
to draw.
Keith Packard floated a patch to increase the Mesa texture size limit to
4096x4096 on the xorg mailing list in April:
http://lists.freedesktop.org/archives/xorg/2008-April/034707.html
With that patch applied I can use Compiz with dual-head.

Stefan: what kind of issues? (I'd like to know what to look out for).
And do they occur directly after launching compiz or after a while?

i965: bump texture limit to 4kx4k
Rendering and textures are limited to 8kx8k, but mesa limits things to
4kx4k, and magic guard band stuff may break on 8kx8k drawing. This is safe
though, and makes compiz work on bigger screens.

Gordon, the commit seems the same as
http://lists.freedesktop.org/archives/xorg/2008-April/034707.html.
However based on based on comment#2, Seems Stefan still has some problem
with this patch.
Stefan, would you like to list the issues when you use compiz with this
patch? It will be helpful for upstream to track what the side effect is?
Thanks

Yes, it's exactly the same patch I have used in the past, but disabled after all.
The issues were, that with compiz enabled changing resolution via RANDR 1.2 (xrandr, ...) weren't possible any longer at all or resulted in strange effects.
See https://bugzilla.novell.com/show_bug.cgi?id=441572 for more details. Unfortunately it contains a lot of confusing comments. :-(

Trying to follow that link to Novell's bug tracker redirects me to a
login page.
I have the following issues with Compiz and xrandr:
* Sometimes after you change the desktop size Compiz doesn't notice
and renders only to a part of the area, keeping the rest filled with
garbage. Sometimes it stops rendering at all, so you see the old
picture (plus some garbage in new areas) and a moving mouse cursor.
Alt+F2, compiz --replace, Enter fixes this.
* Sometimes after I shrink the desktop size mesa crashes the X server
with "Assertion `intel->batch->cliprect_mode != REFERENCES_CLIPRECTS'
failed".
I never thought to attribute those problems to this patch. I suppose I
could revert to pristine mesa and do some testing, if I can find the
time.

... which requires this fix:

Flip the update_dri_buffers test around to only run when DRI1 is active.
Fixes segfaults at startup with DRI2 and load detection, or with DRI
disabled entirely.
BTW, both commits are from xf86-video-intel, the previous two from Mesa
git.
