How about the below?
Idle notify events shouldn't need special treatment, since the pixmap
XIDs of the buffers will be different between loader_dri3_drawable
incarnations, aren't they?
This still leaves the issue that the SBC moves backwards, which could
theoretically result in hangs with apps using glXWaitForSbcOML. Fixing
that would probably require changing the loader_dri3_drawable lifetime
cycle, which would probably be very invasive, if feasible at all. Maybe
we don't need to care about that for the time being, until there's a
real world app running into it.
