Having the extension enabled in the ddx is needed for any test to work.
But when i set a breakpoint on EVERGREENDisplayTexturedVideo() in
evergreen_textured_videofuncs.c, that breakpoint is never hit, even in
depth 24 when XvMC tests work, so i'm not sure if i'm looking at mostly
unused code there?
I guess so. :)
Good, then i don't need to look at that code anymore :).

It only happens if a client wants a fbconfig with alpha channel, for
destination alpha blending etc., as my application happens to. If you
only run glxgears or a desktop compositor like kde-5's, it won't happen
as they only use bgrx configs without alpha.
I sent out a patch which should fix this, please test.
Yes, that patch "[PATCH xf86-video-ati] Always use screen depth/bpp for
KMS framebuffers" makes sense to me and fixes it nicely, as tested under
dri3 and dri2 with glamor and exa:

I assume amdgpu-ddx will need the same treatment, as "Use reference
counting for tracking KMS framebuffer lifetimes" which caused the
problem has been ported to amdgpu-ddx.
