1841952 - Audio can still be decoded on tab process even after bug 1835804

Status: RESOLVED INVALID

(Core :: Audio/Video, defect, P2)

Description

[:gerard-majax]

In bug 1835804 we landed blockage of audio decoding on the tab process, which proved to hit some case which we fixed (bug 1839852, bug 1840371), but telemetry currently shows builds with the changes from bug 1835804, the preference not set to false and yet still reporting audio decoding of at least AAC, FLAC and Opus being done from Tab process, on all platforms.

After a few days of running bug 1844281 landed on nightly:

• we have no more report on Windows and macOS
• we have two clients still reporting wrongful process name tab on linux. They seem to share the following: browser search region changed to PL, AMD G-T56N CPU, 3546MB of RAM and Linux 5.10.181.

This was a bug in the dashboard:

• there can be up to 3 prefs set, dashboard would only show the first one
• those clients after verification of the raw data sets rdd-disabled, utility-disabled and allow-non-utility, in this order.

So in the reporting it would show only as rdd-disabled while we have allow-non-utility that explains the behavior.

We will re-open if telemetry shows real data supporting this.
