Is it possible that there was some change in your system configuration
(hardware or software) that happened around the time you started
seeing this?

I mean, 24.2 was released last August; if it had such a glaring bug in
the display code on a popular platform such as yours, we should have
heard of it by now.  But I don't think any such problems were reported
until now.

One other thing to try is an unoptimized build (CFLAGS='-g3 -O0'),
maybe it's a compiler issue (which version are you using, btw?).
