Overlap on different monitor at windowed fullscreen after startup

Ive noticed that everytime i start up the client there is a small white bar overlapping to a different monitor when it is maximized to windowed fullscreen. I have 3 monitors all 1080p and same scaling on all of them. It doesnt matter at which monitor i run the client. If i maximize it to fullscreen, close it and open it up again the white bar appears. I can fix this by exiting the windowed fullscreen and entering it again. Also deleting the placement file didnt help.
Beta 53 didnt fix this for me its still occuring, i just took the screenshot before the update came out.
