Description Jose Rodriguez 2008-04-15 15:09:20 UTC 
VMD, a molecular visualization tool ( http://www.ks.uiuc.edu/Research/vmd/ ), doesn't display transparent surfaces using the open source driver. Instead, they just stay opaque. It works as expected using fglrx.

VGA compatible controller: ATI Technologies Inc RV350 [Mobility Radeon 9600 M10]
Running Debian Sid with latest Mesa, drm and 2D driver from git.

Just a guess, does this patch fix the issue? If so its the same regression as in bug 15447.

Hi, sorry for the delayed answer. I've been only using VMD for some 4 months, and the transparent surfaces never worked, so I don't think it's a regression. Do you still want me to try your patch?
Comment 3 Jose Rodriguez 2008-05-09 15:55:39 UTC 
Mesa, drm and 2D driver from 2 days ago master didn't solve the problem, so no related to bug 15447.
Comment 4 Andreas Boll 2014-07-07 16:43:31 UTC 
The classic r300 driver has been abandoned long ago.
It was replaced by the Gallium driver r300g.

If you have issues with r300g please file a new bug report with component Drivers/Gallium/r300

Thanks.
