Describe the bug

In Zenless Zone Zero running via PlayCover, setting the in-game frame rate limit to 120 FPS results in the game being hard capped at 90 FPS when my external monitor is set to 180Hz refresh rate. Dropping the monitor refresh rate to 120Hz allows the game to correctly cap at 120 FPS. Switching back to 180Hz immediately drops it back to 90 FPS half of 180Hz.

Steps to reproduce

Set in game fps to 120
In settings set monitor refresh rate to 180 hertz
Game has a maximum of 90 fps
Set monitor refresh rate to 120 hertz
Game now has a correct fps of 120

Expected behaviour

When my monitor is set to 180 hertz the game should have an fps cap of 120 not 90

Crash log

I suspect this is actually a bug in Apple's Vsync and just that no one noticed it yet
