Description Cass Everitt 2017-03-15 01:44:51 UTC
You need this commit of the Vulkan-Samples repo to get something that will run on these drivers, but it crashes almost immediately sometimes, and then will run for 10s of seconds others.

The application needs to call XInitThreads().
Comment 2 Kenneth Graunke 2017-03-18 00:53:14 UTC
Regarding GLSL 4.30 not working...it looks like the app initially creates a GL 4.3 core profile context...but then on atw_opengl.c:2447, it creates a second shared context by doing:

context->glxContext = glXCreateNewContext( other->xDisplay, other->glxFBConfig, GLX_RGBA_TYPE, other->glxContext, True );

That doesn't create a core profile context, so we give you the highest compatibilty context we support, which is OpenGL 3.0...hence GLSL 4.30 doesn't work.
