Everytime I have OBS open when I do something in blender i somehow cant select and vertecies or anything of an object in Edit mode unless I deactivate : limited selection to visible. (next to propotional editing).
Does anyone have an idea what to do or a good alternative for OBS?
You are aware Blender comes with its own recording built-in? (Window–>Make Screencast). To play Render–> Play Rendered Animation.
Download the screencast keys addon here to include visual key and mouse button presses while recording.
