1859866 - MacOS Game Mode interferes with media playback and multiple monitors

Status: UNCONFIRMED

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

Description

[jimbo1111]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:109.0) Gecko/20100101 Firefox/119.0

Steps to reproduce:

Have multiple monitors, be watching streaming media on side monitor, enter fullscreen game on main monitor with Game Mode turned on.

Actual results:

Media will freeze. Every several seconds, it will provide a small choppy update of a few frames + audio, then freeze again. When any app other than the one triggering game mode is focused, media resumes.

Expected results:

Media should continue playing while game mode is active. In other browsers (brave, safari) the freeze does not occur

The Bugbug bot thinks this bug should belong to the 'Core::Widget: Cocoa' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

This does seem to me like an issue that should be fixed in Firefox, but for anybody hitting this issue, you can manually turn off game mode by clicking on the game controller icon in the upper right corner menu thing (when you are tabbed out of the game). That fixed the issue I was experiencing, and shouldn't leave you in a worse state than before Game Mode existed.
