How to fix Lockdown Browser garbled webcam video?

[galacticaledge]

In Respondus Lockdown Browser, whenever I use a webcam, the output is garbled and distorted. I downloaded it from here in my case: https://download.respondus.com/lockdown ... =670114425

For it to render text, I had to install corefonts with Winetricks, and now I run into this issue. From what I can tell, it happens because of DirectShow. Installing native DirectShow with Winetricks makes Lockdown unable to capture the webcam. Using native quartz.dll alone makes it show a plain green output.

Any idea how to fix this? Here is a snippet that might relevant due to it being large:
