I can reproduce the same issue on Firefox 74.0 on Linux (from https://download-installer.cdn.mozilla.net/pub/firefox/releases/74.0/linux-x86_64/en-US/ ), using the reproduction project from comment 1. Note that you need to serve it over a HTTP server for it to run, e.g. python3 -m http.server.
It happens both with Intel HD Graphics 630 and AMD Radeon RX Vega M on my system.
Firefox 73.0.1, Firefox Beta 75.0b8 and Firefox Nightly 76.0a1 do not reproduce the issue, so it seems that it was a regression specific to Firefox 74.0 which has since been solved.
If a Firefox 74.0.1 release is planned, identifying and backporting the fix would be welcome, as this regression likely breaks a number of WebGL-based projects (including many games developed with the open source Godot Engine).

Adding a component to this issue in order to get the dev team involved.
If it's not the right one please feel free to change it to a more appropriate one.

Testing on linux, as per comment 2 instructions. This change broke it: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=5cbf5bb11c585d69321b420f67ffb62544141427&tochange=e1b0906509efa6433978b9f980ec639b7eafbc6d
And this change fixed it again: https://hg.mozilla.org/integration/autoland/pushloghtml?fromchange=24dc59fa7381d59c6c72e45bd65199fb71bf3043&tochange=cad7268d33b0b922373221a1f34b4fbdb7884288
The fixing patch didn't make it in to 74, and instead bug 1617512 was reverted. Unfortunately that doesn't seem to have helped in this case, though.
