Description Sven Arvidsson 2008-03-08 10:01:37 UTC
Textured video has a horizontal line of pink, green, or sometimes blue pixels at the top of the screen when video is shown fullscreen. There's also a short vertical line (usually green) in the lower left corner. 

The left side also shows a white line of pixels if the video contains large white parts.

This only happens with textured video, not with the old overlay. It doesn't show up on a screenshot.

I'm using a Radeon 9100 (r200).

This was previously mentioned in the Phoronix forums, but I couldn't find a proper bug report: http://www.phoronix.com/forums/showpost.php?p=25709&postcount=13

Are you using ati git master?  Some of these issues have been fixed since the initial support was released.
Comment 2 Sven Arvidsson 2008-03-08 12:32:34 UTC
Yes I am, I'm currently using 9d710ee1a44cf2f3a948fbdbe17ef09521cbe744

Can you attach your log, config, and a picture of the problem?

Screenshot of the problem

I was wrong, the pink line does show up in a screenshot. Some image viewers make it hard to make out though.
Comment 7 Sven Arvidsson 2008-07-06 14:12:29 UTC
I just thought I should mention the bug is still present with version 6.9.0.

I was also wrong in my initial report, it isn't specific to fullscreen videos. The line is always there, it's just easier to detect when in fullscreen.

clamp tex coords (r100/r200) for textured video

would this patch help? Maybe tex coords could wrap around due to bilinear filter (not sure though if this really should happen). In any case, someone changed the r300 textured video code to clamp the coords in the past already.
Comment 9 Alan Swanson 2008-07-07 10:40:11 UTC
That patch removes the top line of corruption for me.
Comment 10 Sven Arvidsson 2008-07-07 10:52:47 UTC
Same here, it looks fine now, many thanks! :)
