Screen shot of the issue, from a trimmed trace
It seems that one of the dota2 updates over the last month or so introduced a
regression causing visual glitches as shown in the attached files.
Originally I've assumed to be a mesa regression, but it seems that's not the
case - old, previously working mesa produces the same output.
MESA_EXTENSION_OVERRIDE=-GL_ARB_draw_elements_base_vertex makes no difference,
plus replaying a trace recorded on i965/snb (no issues there) exhibits the same
glitches.
Note: After trimming the trace some textures are not missing and the text
appears block. The trace plus a screenshot of a non-trimmed trace will follow
shortly.</pre>
