Bug Description
For xserver-
[IMPACT]
* Enables SolidFill on fermi and kepler cards, increasing performance slightly.
[TESTCASE]
* start ubuntu software center
* hover over some urls and icons, likely corruption already occurs at this point,
the more you mover over the more it shows.
* This wil not fix it completely, only make it occur less, see xorg-server below for the real fix.
[Regression Potential]
* This should be a safe fix, since it simply enables some code which was already created specifically for these cards, and with some testing it appears to work just fine.
* I expect no regressions, but in the worst case this would result in garbage being sent to the card, which may cause it to do an unexplained hang or (more likely) errors in dmesg and worse glitches since nothing is being shown any more.
[Other Info]
* Doing solid fill in hardware is a pretty nice speedup for those who use valgrind to test code, and also seems to increase responsitivity a little on nouveau without valgrind, since it safes 2 memcpy's on host, 2 memcpy's on gpu, and a memset.
----
For the xorg-server sru:
[IMPACT]
* Fallback to exa with gradients and solid pictures results in visual corruption,
because sometimes the source or mark pixmaps from previous operations are used.
This results in visual corruption when those fallbacks are triggered.
The xxv-nouveau fix helps slightly because it disables fallback for solid fills,
but gradients are still not handled so it still triggers it.
[TESTCASE]
* Start ubuntu software center on a geforce card that has exa acceleration enabled.
* Highlight mouse over items
* Notice display corruption.
[Regression Potential]
* The patch has been reviewed by upstream, but is not yet included (upstream can be slow). The most likely regression would be that suddenly other operations start failing to draw correctly, or worst case cause crashes but I do not think it is likely.

[Original bug report]
Hello,
there are several serious graphic and text corruptions on Quantal with nouveau drivers (which are used by default).
To reproduce:
- Boot a Quantal live system or a fresh installation
- Start software-center.
- Move the mouse in its window or click anything.
Result: Text and some graphics become massively corrupted (See also attached screenshots and short demo video).
I have seen this kind of corruption so far in software-center, ubiquity-slideshow (during installation) and one time on filename text field of gtk-filechooser.
Booting the system with "nomodeset" seems to make the problem go away, as well as installing the propritary Nvidia drivers.
Kind regards,
Jan

Screenshot of corruption
Various Gnome applications regularly have corrupted graphics.
Empathy, Evolution and also Ubuntu Software Center are good examples.
This has happened for a long time and also happens with a 3.2 kernel and git drivers (xorg-edgers).
I have a Radeon 6850, Intel Core i5.
Running Ubuntu 12.04 and it's kernel + xorg-edgers.
