I'm being deliberately vague in the description because there are several symptoms on this page that I expect to change over time when they individually get resolved.

First is this shader compilation error:

Shader validation error: Function [1] 'calc_view_mat' is invalid
   ┌─ :63:5
   │

Just filed bug 1985191 to capture this.

Next is a crashing issue, which is captured at bug 1983609. A sample crash stack from my machine on Windows: https://crash-stats.mozilla.org/report/index/79848f44-287c-4cef-9fa9-083e00250826

I can confirm now that this is all fixed. Noice!
