Mouse stutters when I click in Game

Hello,

so I recently installed Minecraft 1.20.2 and the previous version (just to make sure), I get into a Single Player World or Server (no difference).

After pressing left mouse click I get a 1 sec freezer/stutter and it is really annoying!

Fullscreen or windowed is the same and trackpad does the same thing.

I even installed different launcher: Lunar Client..

Thanks for any kind of help 🙂

Best Regards

Leon
