The patch only disables offscreen pixmaps when the
GLX_EXT_texture_from_pixmap extension is first used, so it's probably an
improvement for people switching between GLX compositing managers and
other means of presentation. However, I wonder if this works with EXA.
It doesn't seem to check that XAA is actually active, and I suspect it's
basically luck if the XAA functions don't crash when it's not. This
needs clarifying before the patch can be applied.

Can you check with him why he hasn't pushed it upstream yet? Last I
heard it had some semantic issues IIRC. The same may be true about patch
20 I suspect.

Indeed. Without this patch, AIGLX should definitely be disabled by
default for etch. With this patch (or whatever ends up getting applied
upstream), we could leave it enabled by default for now and wait for bug
reports once it's in sid or even testing.

I agree. These patches should have very low if any impact outside of
AIGLX.

I think we should go with the 6.5.1 release anyway.
