Quote: "The whole point of AppGameKit is code that works on Windows should work on Mac and Linux. For the most part it does which is brilliant but for some strange reason the mouse side on Mac acts completely different than on Windows. I've tried multiple versions of mouse look code which work fine on Windows but always stick on Mac."
I'd have to agree. I've done some testing tonight and there seems to be 2 main issues:
SetRawMousePosition to recenter the mouse each frame only works if the mouse cursor is hidden. If the mouse ever leaves the bounds of the window it becomes visible and this doesn't recenter it properly. When visible, it can hit the edge of the screen problems. This seems to affect both mac and windows though and can be resolved by setting it to hidden again each frame.
More importantly for mac, if SetRawMousePosition is called every frame, it prevents all mouse movement entirely. On windows it allows you to capture the amount that the mouse moved from the center during the frame.
detection of movement can be forced by adding a minimal delay to the positioning, but this then creates a pause which prevents smooth mouse looking and isn't really a solution.

after some further testing, looks like you need at least 200ms between calls to set the mouse position in order to detect any mouse movement from that position, at least on my machine, which is terrible for camera handling.
