--- Comment #5 from Deve <deveee at gmail.com> ---
It uses GLX, but I can test EGL if you want (it's already done for Wayland, but
disabled by default).

glxinfo doesn't report ANY config with srgb-capable framebuffer, even though
B8G8R8A8 IS srgb-capable (we use GLX_ALPHA_SIZE=1 for intel since mesa 10.6 to
force srgb-capable fb).

Most likely I will eventually get rid of all "glEnable(GL_FRAMEBUFFER_SRGB);"
calls in STK because it causes too many issues and we need it for OpenGL ES
renderer on Android anyway.

And the reason of this bug may be that old mesa was ignoring the
GLX_FRAMEBUFFER_SRGB_CAPABLE_ARB, and now it recognizes it and thus fails
because there is no config with srgb-capable framebuffer?

And btw. current git STK doesn't crash anymore.
