So when I boot the game up it automatically wants to use both of my monitors as one and when I go to change the resolution or try to set it to windowed mode it gets locked into this fullscreen/windowed mode thing. I have contacted tech support on the issue and I have checked my drivers which are up to date and I do not have EyeFinity or anything of the sort set up on my system.

I have already tried to do the following fix and it did nothing:

Here is the info on my drivers:

glxinfo | grep "OpenGL"
OpenGL vendor string: X.Org
OpenGL renderer string: AMD Radeon (TM) R9 380 Series (TONGA, DRM 3.19.0, 4.14.201-162.lts, LLVM 10.0.1)
OpenGL core profile version string: 4.6 (Core Profile) Mesa 20.1.9
OpenGL core profile shading language version string: 4.60
OpenGL core profile context flags: (none)
OpenGL core profile profile mask: core profile
OpenGL core profile extensions:
OpenGL version string: 4.6 (Compatibility Profile) Mesa 20.1.9

OpenGL profile mask: compatibility profile
OpenGL extensions:
OpenGL ES profile version string: OpenGL ES 3.2 Mesa 20.1.9
OpenGL ES profile shading language version string: OpenGL ES GLSL ES 3.20

On top of everything else, this is the only game in my library that does it.

If anybody has any suggestions, I would appreciate it.
