After installing 3.4 not able to work in full screen anymore

I've done a clean install of 3.4 yesterday and i discovered i cannot work in full screen anymore. There is always white bar at the left of my canvas which cannot be taken out as far as i am aware. Is this a bug or is there another way to get rid of this white area. Any help to solve this annoying issue is appreciated. See picture below:



Hi MrBlond,

Which OS are you using? Can you please try to double-click the KNIME Explorer tab and then try again to maximize the workflow tab?
