When new specifications are made available it's not like the old one

specification would change anything.
I paid about €3000 for my new PC, including €300 for the graphics card
with HDMI 2.1 output and about €2000 for my new Samsung OLED TV with 4
HDMI 2.1 inputs, and now you are telling me that I will not be able to
utilize them fully because the cable specification has not been made
publicly available?
Did someone forget to pay the people that design the cables? Because
that is what it sounds like. Why does Linux stay behind?
Sadly the HDMI forum only provides the HDMI specification under a special license which
prohibits implementing it in open source drivers.
Since membership inside the HDMI forum costs 15000$ annually, i suspect that the HDMI forum
is abusing its power to force people to join (and pay).
I can feel your disappointment, but there is nothing we can do which does not land us in court :(.
Thanks,

In the meantime I also checked the framerate synchronization through
glxgears at different resolutions and framerates. This does function
as expected. Although I haven't yet inspected the glxgears source
codes in detail, the OpenGL double buffering must be functional up to
some level. This means that the problem must be confined to GTK and
the GtkGLArea widget. Using GDK_BACKEND=x11 I do get a double buffered
context, but the default buffer does not alternate between GL_FRONT
and GL_BACK.
Yeah, that's not how double-buffering works in GL. The draw buffer is always GL_BACK, SwapBuffers doesn't affect that (it just may internally change which actual buffer GL_BACK refers to).
I don't see more context about the issue you're investigating, any pointers?
