Describe the bug

PlayCover: 2.0.1 (188)
macOS: 13.1

screen recording of the bug in action

while the cursor is released, clicking mouse LMB causes huge FPS drop in-game. if the cursor is focused/using keymapping, no FPS drop occurs. The severity of framerate drop is kinda proportional to how much and how fast you're clicking in a short span of time. As you can see in the video at one point I clicked faster so the FPS dropped harder.

Dunno if this happens with other games too since I mostly play Genshin, this has happened in previous playcover versions as well though I don't recall how far back.

If it makes any difference I had Genshin open as a window on Desktop and was switching back and forth between Firefox which was open in full-screen.

sometimes the bug still happens after restarting the game, sometimes it goes away on its own

Steps to reproduce

not able to reproduce this consistently, it just happens sometimes. i will update this when i figure out what 100% causes it

Expected behaviour

no FPS drop when clicking mouse while cursor is 'released'

Crash log

no crash

What version of PlayCover are you using?

Nightly/beta

What version of macOS are you using?

Ventura (macOS 13)
