Sketchy support for ultra widescreen making the game...difficult to play

I’ve been playing GDT since the pre-steam days (<3 to GHG, you guys are awesome) but I only recently ran into this issue as I upgraded my monitor to a resolution that GDT only technically supports, apparently.

I’m currently running at a resolution of 2560x1080. The game is totally playable at this resolution, all of the menus work correctly, etc.
There’s one issue though.
The entire game is shifted to the left. So much so that at the final level, the name of staff member #2 is actually cut off. Most of the R&D lab is on-screen when on the development part of the “level” (likewise most of the “center” part is on screen while looking at the Hardware lab), but of course you still have to scroll way over to get there.
And this leaves most of the screen (basically everything after the first 1920 horizontal pixels, I presume) not even being used. As I said it’s totally playable and everything, but god is it an inconvenience.

Screenshot to show what I’m talking about:

As you can see, the UI elements normally on the right are on the right, and the UI elements normally on the left are on the left, but the UI elements normally in the middle are shifted to the left by a significant margin.
Clicking anywhere on the screen here brings up the typical dialogue box, so it’s not like the R&D lab being visible even adds anything to the game (which would be cool).

And on the R&D lab:

Now most the screen is just whitespace. Not entirely malignant…but it’s really annoying.

The reason is obvious, and honestly, I doubt that is a supported resolution.

EDIT: Why do you even scroll that way? You can see it from there.

You can’t access the R&D lab’s features/menus without scrolling over to it, even though you can physically see it from the main screen.

And I know it isn’t a supported resolution, I just figured that there’s gotta be some way to “center” the view again, right?
