corrupted text. Note that some shows the wrong text completely
I experience wholesale corruption on 00:01.0 VGA compatible controller [0300]:
ATI Technologies Inc Device [1002:9806]
Linux (Ubuntu) 3.2.0-4-generic
xserver-xorg-core 2:1.11.2.902+git20111209+server-1

[drm] initializing kernel modesetting (PALM 0x1002:0x9806 0x1043:0x84E7).
[ 12.711246] [drm] register mmio base: 0xFEB00000
[ 12.711249] [drm] register mmio size: 262144

The attached screenshot shows typical issue - wholesale corruption in GMail.
Amusingly, taking a screenshot does not make the thing go away, it just changes
which text is corrupted.
On Redwood I get occasionally minor corruption in Firefox.
On r300 x1600-ish I get similar effects since I disabled vline waits,
occasionally.
Not sure this is related (either to the vline waits or the r600 issue). The
corruption on r300 happens sometimes in Evince or gkrellm (or maybe Firefox),
not in terminals. I did not try re-enabling the vline waits or downgrading X
because it's hard to tell if the issue is present or not.
