--- Comment #13 from Ilia Mirkin <imirkin at alum.mit.edu> ---
Olivier,

I'd like to help you, but I'm just not sure how -- I don't have Wayland (or any
interest in setting that up), and your traces appear incomplete. I don't know
why - I've never seen that before. But they don't create contexts. Compare your
Xephyr trace, which has

1 glXChooseFBConfig
...
9 glXCreateContext
10 glXMakeCurrent

While the Xwayland trace has none of those. Paradoxically, it starts at call
31. Perhaps you have a non-egl-enabled apitrace? Also note that there's not a
single instance of UseProgram or any other shader-related items in the XWayland
trace.

Does the Xephyr trace exhibit the problems for you when replayed? If so, I can
investigate that. However on my GK208 (or with llvmpipe), when replayed, it
doesn't appear to render anything.
