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.

fix fragment.position

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.

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.
