I can't reproduce this here with Mesa 7.5.
I'm checking in some fixes for glxcontexts.c though.

Ian, can you reproduce?

I'm increasing severity since it impacts real-world application.

the issue also impacts our glean case (texgen,vertattrib),I think it is a regression in mesa 7.5 branch. I am trying to bisect.

i915: Don't put VBOs in graphics memory unless required for an operation.

This saves doing swtnl from uncached memory, which is painful. Improves
clutter test-text performance by 10% since it started using VBOs.

This was fixed shortly after mesa 7.5 rc4 released. debdiff attached containing the patch incase it's important enough to patch before 7.5 final is released and synced.
