[BUG] SteamVR Dashboard Desktop View Incorrect Mouse and Display Mapping

[Semperverus]

Describe the bug SteamVR Dashboard Desktop View incorrectly maps mouse if using multiple monitors. The input region for the mouse does not line up with the actual monitor view itself, but instead will act like there is a canvas in the shape of all of your monitors combined that seems to be locked to the lower region of your view, with the very bottom aligned to the SteamVR dashboard bar.

To Reproduce Steps to reproduce the behavior:

1. Connect more than one monitor to PC
2. Start SteamVR
3. Open SteamVR dashboard with menu button
4. Click "View Desktops"

Expected behavior This should work exactly as it does on Windows: You point at a spot on the display area, your mouse moves to that spot that you are looking at.

My secondary screen sits on top of my primary screen; the desktop view places them the other way around but the mouse still act as if they're where they are supposed to be (I have to aim at an empty area on the bottom to move the cursor on the screen that is being shown above and vice-versa, and the real screens are the other way around. And if I'm not mistaken, it seems to ignore resolutions, or rather, it squishes the bigger screen to match the size of the smaller screen I think.

I think I may have a similar problem on Windows, but havent found anything on that bug yet. My window-setup is like this:

with the left monitor being 19201080 on 100% scale and the right 38402160 on 150% scale. Sometimes the position of pointer (and visual (Windows-)mouse) gets somelike scaled towards the top left corner of the left screen. Meaning if I click somewhere the click is registered offset towards the bottom/right doubling the distance to the top left. This streches over both monitors, so that I can even interact with the primary display if I click somewhere on the right half of the left display.

I havent figured out when exactly this happens. Its sometimes just there.
