I managed to create some corruption with an xterm above xpdf. It looks  different
than the original corruption, so I think it's safe to say it's a different bug:

This was without xcompmgr running, I don't think I would have seen it otherwise.
Actually, it turns out it's really easy to trigger as well, so I can more easily
test patches now. Unfortunately I wasn't smart enough to store the bisecting kernels,
gah!

I tried with both your patches, as well as the HIC poking patch, but I still get it.

I'll try to pinpoint more exactly when this started to happen.

Greetings,
