some day I will either have to get ANGLE to build and integrate it with touchHLE, or make touchHLE call glReadPixels() every frame, and it remains to be seen which of these is more painful
dear GPU experts: is it okay if I call glReadPixels() every frame. like yes I know that serialises the entire pipeline but suppose I only do it right at the end of the frame before compositing it to the screen. can I get away with this. I have… special requirements ;_;
@hikari what's the special requirement? 🤔
@joseph_garvin for touchHLE, my emulator project, it would be extremely useful if I could share images between GL contexts, but for some reason (perhaps because they have different GL versions), I can’t get proper sharing to work, so this is a desperate idea for achieving it another way
