<pre>I just checked the patch and nothing changed for me (with GLX, I didn't test
EGL). I patched mesa version 4d807d7fe272db97fb9e20800872d5970fa2696d.
If you run current git STK, there are two warnings in console:
[warn ] irr_driver: Created visual is not sRGB-capable. Re-creating device to
workaround the issue.
[warn ] [IrrDriver Temp Logger]: Level 2: No sRGB framebuffer available.
The first one happens for intel when
glGetFramebufferAttachmentParameteriv(GL_DRAW_FRAMEBUFFER, GL_BACK_LEFT,
GL_FRAMEBUFFER_ATTACHMENT_COLOR_ENCODING,
¶m);
returns GL_LINEAR, so this is true for all mesa versions >= 10.6 (precisely
since MESA_FORMAT_R8G8B8X8_UNORM has been added). In this case we make an ugly
hack and re-create device with alpha channel, that forces to use
MESA_FORMAT_R8G8B8A8_SRGB.
The second warning happens when request a config with
GLX_FRAMEBUFFER_SRGB_CAPABLE_ARB fails. So then we try to get a config without
this flag.
And glxinfo still doesn't show any srgb configs for me. Are there some
particular requirements, such as current libdrm, DRI2/DRI3 etc...?</pre>
