I'm not exactly sure when the problem first occurred, but it's been
quite a while, definitely more than 6 months. Here's a screenshot of the
problem:

This is with mplayer using Xv, on standard definition video in
fullscreen. Note the gree, red and blue color bars at the bottom. They
always appear, but naturally, they're most visible in dark scenes. It's
not an mplayer bug it seems, since pausing the video and going out of
fullscreen and then back makes them go away temporarily. Also, they
never appear with AMD's binary fglrx driver or on non-radeon cards.
The problem, as I mentioned already, is an old one. Right now, I'm at:
Radeon HD4870
kernel 2.6.35_rc6
xf86-video-ati Git master
Mesa Git master
X server Git master
I've made another observation (accidentally). The problem does never
occur when compositing is active. KDE "unredirects" fullscreen
applications by default (meaning that compositing gets disabled).
However, if I disable that (for example by right clicking somewhere so
that SMPlayer's or VLC's context menu appears, which also disables the
unredirecting and re-activates compositing), then the colors are
perfectly fine again.
Does that mean that it could be a bug in KDE's compositor?
