This really sounds like video driver issues here. I'm reassigning this
bug to both packages for now. However, since fglrx is developed by
AMD/ATI, I persume they would be in the best position to actually do
something about that.
I might agree except that:
1) my desktop display is fine. I didn't have to do anything with gimp,
gwenview or any of my other desktop applications. It was just the video
applications that were messed up.
gimp and other 'normal' applications do not require hardware assistance
in the same way as a media player needs it. Xv is useful to lower CPU
consumption in media players. X11 backends makes media players to behave
like other 'normal' applications, at the expense of wasting CPU time.
2) the Kafeine fix was a simple setting that was off while mPlayer
needed a different output to be selected. It appears that the fglrx GL
implementation is faulty, since I can't get good output from
it. However both Kaffeine and mPlayer have no problem with normal x11
video. Kaffeine picks x11 automatically while mPlayer needed to be
told to use it.
Video drivers sometimes offer only limited xv ports, which limits the
number of applications that can simultaneously use the xv extension.
Unfortunately vlc's x11 video output, which works fine for the other two
players, produces bad output. And there doesn't appear to be a way to
reduce the extreme contrast like there was in Kaffeine.
The application could indeed influence this. However, I see little point
in working around bugs in proprietary display drivers like this in open
source applications.
BTW: as I mentioned in the beginning, I tried to use the open source
drivers but the ati, radeon and radeonhd drivers don't work with this
chipset and the vesa driver is really only good for debugging.
Unfortunately, right now there is no working open source driver for the
Radeon HD3300 (at least not in Debian). Hopefully AMD's efforts to open
up its hardware will change this.
