Requesting help with a project.

Hey all!
I was wondering if anybody could donate some of their time to help me out with an issue I can’t seem to resolve.
My project is an animated wallpaper engine running on monogame.
Currently it’s titled “LivingPaper”, but that’s just because “Untitled” already existed in my projects directory.

Also note, I have three monitors.

Anyway, the problem is that when drawing on any monitor other than the far-left, nothing is shown even though all coordinates look correct. I don’t think this is related to the nature of the project since drawing on the left monitor works fine.

I’m probably just misunderstanding something here.
I’ve recorded a video showing the problem and I’ll upload the project to github as soon as I can.

Note that I had to record it all with my phone because recording all three monitors with software with good enough resolution wasn’t going to work out.

Still broken; I’ve uploaded it to github finally if anybody out there is ever interested
