Description Gabriel Mansi 2007-08-15 18:50:23 UTC

I think this assert is no longer valid:
assert(sz == vmesa->total_alloc[heap])
in via_tex.c line 429

There are a few linked lists to maintain references to the textures in use, one of those lists contains the textures pending to be released but that assert does not consider it.

Comment 1 Diego 2007-10-16 07:08:05 UTC

There are many, many bugs depending on this assert on the net.
Googling "viaSwapOutWork" will show some of these.
I have a similar problem: when I use glCallLists() on lists returned by glXUseXFont(), the first time I run my program, I have this error:

via_tex.c: viaSwapOutWork: Assertion 'sz == vmesa->total_alloc[heap]' failed.
Aborted

from the second run on, everything runs fine.

If this assert is unnecessary, I think it should be removed as soon as possible, since it is the root of many other bugs, for example:
