(Get the code!)
The glitches look exactly like what I've seen on my computer. I think that it is caused by some sort of pixmap cache corruption, because it will affect all occurrences of the corrupted letters. Also, I've seen repeating corrupt patterns in other places as well, such as window decorations. Both of these effects are shown in the attachment.
Apparently the intel driver man page has out-dated information about the default acceleration method, as it says that XAA is the default, even though it seems to be EXA. I guess that's why my experiments with XaaNoPixmapCache etc. didn't give any results. I'm now using XAA, and at least so far seems that the problem doesn't show up.
