Windows 10: Strange bug with fullscreen youtube vidoes on second monitor in chrome

I am experiencing a strange bug in chrome, whenever I put a youtube video into fullscreen mode, I can see my desktop along the left side and the top. I'm not sure what is causing this bug, as it has only started happening recently and only on a monitor without a task bar. I have provided a screenshot to make things more clear.

Using 2 monitors

I just got my second monitor in, hooked it up, and got everything setup. But one thing that bothers me, is that when i try to run fullscreen games on my primary monitor, i cannot press pause (which usually shows the mouse) and move the mouse over to the
second monitor to do other things like click another youtube video, or anything. The mouse just stops at the border for the first monitor. Is there a way that i can change a setting somewhere that allows me to run a fullscreen game on one screen while being
able to operate on the second screen? Note: This is allowed if i watch fullscreen youtube videos.

 

Possibility to move windows to other monitors with 'windows key + shift + arrow keys' on fullscreen youtube with windows 10?

I've noticed that moving windows between monitors with 'win key + shift + left/right arrows' does work with all kinds of windows but it behaves weird on fullscreen youtube videos. I currently have 3 monitors
connected and what 'win key + shift + leftarrow' does is move the fullscreen video to the right monitor and 'win key + shift + rightarrow' moves it over to the left monitor. Notice that left and right are reversed, and that the primary middle monitor can't
be reached with the shortcuts. This behaviour happens both in chrome and firefox. On microsoft edge, the fullscreen youtube video doesn't seem to move at all. I'm not sure if this matters but i'm using an Nvidia 960m graphics card with the latest driver. I
have windows 10 updated to the latest version.
