1) Is a the 'non vsynced pageflipping' issue present on Wayland?
2) Will 'ping-ponging' be an issue on HSA systems? AMD CPU with an AMD dedicated card. I haven't checked out the HSA spec so I don't know if you can request to be put on graphics RAM vs system RAM or if you really are just saying "I need a buffer with xyz size" and get given back a pointer and youre blind to whether or not its on DDR3 ( / 4) or GDDR5. Just a thought that came up, figured I'd throw it in haha
One side question: Does open source radeon driver support 4K display now?
