Description of problem:
Using desktop effects (compiz), video players (like VLC, Totem) don't display
the video for the movie unless the window is moved to a particular location.
This location repeats across the screen. I vaguely remember a similar problem
on NeXT hardware running NeXTSTEP if that rings any bells for the people working
on this bug.
I'm using the free software ATI Radeon driver that ships with FC6's x.org and an
ATI Radeon 9200 SE video card (an AGP card).
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. Enable desktop effects.
2. Start a movie player and watch a movie.
3. Odds are good you won't see the movie until you scoot the window into a
particular position on the screen. There are many such positions on the screen
and they seem to be spaced regularly, but I don't know how regularly.
The video display is blank. Moving the window shows odd flickers of portions of
frames. Then when the window is in the "right place" you see the image you
The movie displays no matter where the window is.
Disabling desktop effects makes the video display work normally.
I don't seem to have this problem. I can play a video with totem and it
displays correctly no matter where the window is placed. In fact, it continues
to play even as the window is resized and moved. It even plays in the
application switcher (ALT-tab). I am using Fedora Core 6, updated as of 18 Nov
06. My computer is a PowerPC iBook with a video card identified by X as ATI
Technologies Inc M9+ 5C63 [Radeon Mobility 9200 (AGP)].
Playback seems to drop frames when the video is scaled large, but this is a
separate issue (because XVideo is not supported by compiz?)
