--- Comment #7 from bastian.beischer at rwth-aachen.de ---
This bug is triggered by a new error (GLXBadFBConfig) which is emitted in Mesa
21 (maybe only in certain cases, specific HW, supported GL version, ...).

If you read https://gitlab.freedesktop.org/mesa/mesa/-/issues/3969 you will
understand the details. The mesa developer suggested to wrap the call to

pglXCreateContextAttribsARB

in dlls/winex11.drv/opengl.c (create_context function)

in X11DRV_expect_error in order to turn the error into a warning. I think this
is a fine solution. However, X11DRV_expect_error only works if a X server
request is made, which does not happen in this case (see the mesa gitlab
ticket).

In any case I don't think mesa developers will change anything so it should be
fixed here.
