Fullscreen visual issue with 2 monitors (vertical white line)

Hello. 

I used 2 monitors: 1 - Left, 2 - Right. After starting Rider, he opened in full screen in the left monitor, and I see a white vertical line in the right.
After clicking the fullscreen button twice Rider fit on monitor 1 without that weird vertical line in the second.

Please fix this white line :)
