Cross-regressions between wine and mesa: how to handle them?

Hello all.

More than a month has passed since the bug report, and Mesa devs
haven't said anything. What should my further actions be? I suppose
some of the following:

1. Wait more
2. File a bug at winehq and hope that something could be done as a
(automatic) workaround
3. Not rely on this being fixable and tell all users with i915 and
similar chips to patch either wine or mesa, or maybe use some registry
overrides in wine (UseGLSL and the like)
4. Something better?
