Is this reproducable? Can you clarify what mouse cursor movement you exactly do until the cursor jumps away (s. below)? Does this happen in all documents? can't reproduce with TeXstudio...

This happens even if you disable line numbers, folding and Line Change States (will also deactivate line marks), i.e. no editor side panels visible. So moving over the left edge...
