Correct, that's EGL_BAD_MATCH. There are very few ways that can
happen; by far the most likely is that Qt has chosen an EGLConfig
which does not correctly correspond to the format. (If it was an
impossible format/modifier combination, then this would be already
caught when allocating the gbm_surface.)
Either way, it seems quite clear that the VOP2 driver is totally fine
here, and that you have a Qt (likely) or Mesa (tbh less likely) issue
to debug to get the app working.
Cheers,
Daniel
