Having 3+ controllers/trackers connected with MVP installed breaks display

[vcortex91]

When I have 3+ devices (e.g. 2 controllers + 1 tracker/LIV virtual cam) connected in Beat Saber, only the bottom quadrant of the display is rendered. However, 2 devices connected (e.g. 2 controllers, or 1 controller + 1 tracker) works fine. Also, if I delete the MVP dll in the plugins folder, the issue goes away as well. Here is the headset mirror of the issue:

I heard from someone that the BeatSaberMultiplayer mod with the PTT button set to one/both grips causes a similar issue. However, I tried unassigning the grip buttons with MVP still installed and the issue didn't go away.

Here is a log output from "C:\Users<Me>\AppData\LocalLow\Hyperbolic Magnetism\Beat Saber\output_log.txt" that I believe is relevant:
