--- Comment #2 from wanderer@fastmail.fm 2010-04-25 16:45:55 --- As I said, I'm using the fglrx video drivers - the latest available via Debian stable/testing's fglrx-driver package - and this problem first manifested after I had updated both them and the xcb packages. There is no more recent graphics driver to update to.
Downgrading would be a reasonable suggestion, except that it's a royal pain, especially since this is the only version so far of these drivers to support Xorg 1.7; downgrading them would require downgrading X as well, and having done it at least once, I know that's nontrivial. (I'm also *not* eager to try downgrading fglrx, since even installing or upgrading it is a complicated process, compared to the nVidia drivers I was using last time I needed to downgrade X.)
