1816559 - Enable screen recording when GPU sandbox filesystem blocking is active

Status: RESOLVED FIXED

(Core :: Security: Process Sandboxing, defect, P1)

Description

[Chris Martin [:cmartin]]

In Bug 1811991, screen recording was broken causing tests based on BrowserTime to fail.

Screen recording currently relies on the GPU process being able to write to arbitrary files in the filesystem with the recorded frames. This is not allowed when the GPU sandbox is in full force, so we will have to find a workaround.

Marking S2 because this is a security feature clashing with our automation, so we really want to fix this.
