Playing video gone wacky?

[Tom Horsley]

Some recent update has completely messed up video playback on
my system. I believe mplayer uses the 'xv' output by default
and it now looks like it only manages to update a band here
and there on each frame. The picture looks like it was run
through a shredder and pasted back together with the wrong
strips :-).

If I play with the 'gl_nosw' output driver, there are no problems
(so that's the obvious work around).

The only X related update I notice recently was a bunch of
mesa libraries on April 30th.

But I have all the same mesa libs on my system at work and
it has no problems. At work I have the radeon driver, at
home I have the intel driver, so maybe it is an intel driver
problem (but the intel driver hasn't been updated recently).

Any idea what component I should report this against?

Anyone else see the same thing? (It isn't isolated to
mplayer - I get the same corruption in vlc, etc).
