--- Comment #65 from tempel.julian@gmail.com --- @Nicholas Since this commit, the modesetting driver shows the same behavior as xf86-video-amdgpu: https://gitlab.freedesktop.org/xorg/xserver/commit/f0d78b47ac49977a6007f5fe0...

So, now only xwayland isn't affected. But I think this can very well be just because Wayland compositors yet don't support turning compositing off in fullscreen. We might see the same effect as on Xorg, where keeping some compositors enabled seems to "fix" the issue (at the cost of high input latency, other performance issues and non-functional FreeSync).
