Minecraft recordings wobble?

Today I wanted to record minecraft with OBS and when I looked at the recording it wobbled. No lags, everything wobbled every 2 seconds and I wonder why.

My PC doesn't recognize Minecraft as a real game either, e.g. Discord should actually say ______ plays minecraft but it doesn't say that.

Maybe your pc is too weak or you have set it incorrectly… Or Minecraft has to be reinstalled
