The issue is "cemu was developed against a specific GL implementation,=
 and
doesn't work with other perfectly conformant GL implementations".

In this case, you're getting a GL 3.0 compat context. It tries to enable
GL_PRIMITIVE_RESTART, which was not available in GL 3.0. With
NV_primitive_restart, which is most likely exposed, one needs to use
GL_PRIMITIVE_RESTART_NV, which conveniently is a different value.

As I mentioned, you can try the COMPAT tail to the version override so you =
get
a compat context, but lots of stuff won't work - there are good reasons why
mesa doesn't expose high-versioned compat contexts.

You are receiving this mail because:
