Pop OS can't maximize window

I have tried a bunch of distro’s and it appears Pop OS is the most smooth and reliable for running games through Lutris. However, it is also the one distro I have the following issue with. It will not allow me to maximize to fullscreen. It seems to be in the correct resolution and seems to think it is maximized, but it is not. I have played with all sorts of settings and nothing changes this. Has anyone seen this or know a fix? Only getting this on Pop OS.
