This is a follow-on question to this thread:
We have a set of textures we redraw using FBOs. We’d like to be sure that the driver doesn’t ghost them.
If we issued a sync object after each read submitted for one of these textures, and then on submitting a write request checked whether the most recently-submitted sync object for that texture was signaled, would that be a valid test for ghost creation?
(This is in absence of a PowerVR driver or emulator that warns on ghost creation, in an attempt to emulate this.)
