All games tested with Graphics API Visual Indicator switched on show a red “BLIT” indicator, GSync indicator doesn’t show up. Not sure if it’s an issue with mutter not redirecting fullscreen windows, something in the config, or the driver.

I resolved my issue by installing gnome-shell-performance and mutter-781835-workaround in the AUR and now they allow flipping mode, perhaps there was something else I did but pretty sure it was those two packages that resolved the problem for me.
Yeah real shame that dual monitor support isn’t a thing, nor does it work with window mode or fullcompospipeline, quite limited compared to how well it works under windows. Would have been nice if linux had fast sync…
