User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:74.0) Gecko/20100101 Firefox/74.0

Steps to reproduce:

1. Open figma.com
2. Open a project for edit/ view

When I open the console I see the following log messaged:

reconnecting to realtime in 2000ms 
release_manifest_hash: 36862c31210ea4b4086d636498c134a0

[Fullscreen] Using WebAssembly

Fetching https://static.figma.com/fullscreen/8a319dec07209cedbe962fc5ab067574ce582133/compiled_wasm.wasm.br started

but also an error

TypeError: can't access property "match", glslVersion is null

for the stack trace please see the attached image. This error is not thrown in FF 72 without WebRender enabled and it worked before enabling WebRender.

OS: Ubuntu 19.10

Actual results:

Figma throws an error (if you try to open the project by a direct link) or it keeps loading forever (if you access the project from the dashboard).

Expected results:

The projected should have been shown. No error should be been thrown.

Weird. Does other WebGL content work for you with WebRender enabled?

I just tried a couple of the demos here and couldn't see any problems. Do you think this is rather an issue on the side of figma?

I was unable to reproduce on Ubuntu 18.04 with nightly and 72. Can you supply your about:support?

I don't know if/ what has changed, but since the weekend it's working again on Nightly.
