screenshot fragment that demonstrates the corruption
- latest mesa driver from git
- latest libdrm from git
- latest xf86-video-ati
- ATI Radeon HD 3200 Graphics (ChipID = 0x9610)
- DRI, AIGLX, EXA enabled
- KDE4 with OpenGL desktop effects enabled
Corruption happens only with text and only when the text is put in.
The corruption happens while simply entering/editing text and also while moving cursor through the text.
I believe that this might be a known issue.
I am reporting it for the sake of proper tracking.
I am attaching a screenshot taken after moving cursor though some text in input box of google search (in firefox).
This will go to 'master' too, of course?

7.6 branch gets merged into master regularly, so yes.
Thank you for fixing this!
Everything is perfect now.

corruption from vertical cursor movement
I probably was too fast to mark this bug verified.
First, the change is not yet merged to master (I did a local cherry-pick to check it).
Second, it looks like still get some corruptions although they are much rarer and much harder to reproduce. Now, they are mostly happen from vertical cursor movement, e.g. in thunderbird's mail composition window.
The previous testcase, fast horizontal cursor movement, doesn't produce any corruption anymore.
Given comment #5 I am re-opening this bug.

I am not sure if this kind of corruption is related to this bug.
I see this with thunderbird while opening/downloading a rather big messages.
Should be fixed now:
Tested and verified with git master.
This time I made sure to try to reproduce the symptoms in every way I could imagine.
Big thanks to all who did this!
