I'd like comment on the user above, sorry I should've been more specific in my wording. W10 supports several multitasking features, one of them is "Snap". This feature allows an user to arrange windows automatically by having windows dragged to the sides or corners of the screen. It normally will show up with a pre-view of how it would look before it "snaps" into place. More about snapping here: https://www.windowscentral.com/how-use-snap-assist-windows-10-0

By going into "full screen" I was luring to the full screen found in the drop down menu, or the F11 key. If the window itself is maximized I do not experience the effects off this bug.

As well as that, this started to happen recently, once I upgraded my windows machine from 1803 to 1809, the (still somewhat buggy) October update. Once I upgraded I found out that my chrome like file explorer, started to bug out on me as well. (Clover from ejie.me) However that is using a deprecated version of chromium.
