https://bugs.freedesktop.org/show_bug.cgi?id=99400 --- Comment #13 from Ilia Mirkin --- 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. -- You are receiving this mail because: You are the assignee for the bug.
