This doesn't show as an error here, with your suggested reproduction
instructions. From eglDestroySurface:
'If the EGL surface surface is not current to any thread,
eglDestroySurface destroys it immediately. Otherwise, surface is
destroyed when it becomes not current to any thread.'

Which GL stack are you using? The comment above the no-surface
MakeCurrent in gl_renderer_destroy() is probably pretty telling, that
Mesa once had a bug.

Regardless of this, I am inclined to apply it to match the others,
even just so we can be sure that the destroy takes effect immediately.

Cheers,
Daniel
