blender: swrast/s_span.c:1327: _swrast_write_rgba_span: Assertion `colorType == 0x1401 || colorType == 0x1406' failed.

After downgrading libgl and ati-dri to 7.11.2-1 versions it works ok.

Steps to reproduce: try to start blender on mesa 8.0.1 (and ati drivers)

A simple rebuild fixed it for me here. I'm up-to-date with [testing]

Try running: LIBGL_ALWAYS_SOFTWARE=1 blender and report results.

Sorry guys, this particular PC is in my family house and I'm there occasionally. Right now I can do very limited testing.

@Uli Armbruster (Army): what kind of rebuild you're referring to?
Comment by Uli (Army) - Saturday, 17 March 2012, 21:42 GMT
I simply rebuilt the package using makepkg. The latest version (3:2.62-3) works here. What could be is that I had a different error...Didn't look at yours too closely. So my comments could be useless :X

Sorry for big delay but I don't have direct access to that particular PC, I did "LIBGL_ALWAYS_SOFTWARE=1 blender" and it works, out of the repos blender still doesn't work on this hardware

Use the workaround for now and tell blender devs upstream. This seems to be purely a r200 bug that they might be able to fix. Also tell mesa and see if it's their fault.

blender upstream bug report:

You should add that LIBGL_ALWAYS_SOFTWARE=1 works.

Dan Eicher from Blender: "Yeah, that's a mesa bug."
Comment by Campbell Barton (ideasman42) - Monday, 16 April 2012, 03:40 GMT
This is a mesa bug for sure, I managed to work around it by passing an invalid argument to an OpenGL call in blenders icon drawing function (but then no icons are drawn).

Attached patch.

This report should be made to mesa.

Well shouldn't this bug be closed then? Blender and Mesa (I think) are now aware of the problem and there's nothing more we can do.
Comment by Andreas Radke (AndyRTR) - Saturday, 19 May 2012, 19:46 GMT
Mesa 8.0.3 is in the repos. Has this been fixed?

If not we need a MESA upstream issue to follow - then we can close this one.

I'll check this next time I'll be near that PC (which probably is wednesday)
