swayidle enters idle state during YouTube/Plex playback in browser

[wadeduvall]

Previously, swayidle would block during playback in the browser. Recently, this seems to no longer work (maybe 1-2 weeks ago this started). I'm running ArchLinux (btw) and my browser is Firefox.

System details:

$ sway --version
swayfx version 0.4-cf59f67 (May  2 2024, branch 'master') (based on sway 1.9.0)
$ paru -Qs swayidle
local/swayidle 1.8.0-1
$ firefox --version
Mozilla Firefox 125.0.3
$ paru -Qs systemd
local/systemd 255.5-4
    system and service manager

I can test on native sway if you think that will resolve the issue.

Here is the debug output during YouTube playback:

$ swayidle -w -d \
          timeout 300 'swaylock --grace 3' \
          lock swaylock \
          before-sleep 'swaylock'

I'm also open to this being an issue outside of swayidle, I'm not exactly sure what triggers the idle state.

[kennylevinsen]

The idle state is triggered by sway once the specific activity timeout is hit, whenever no idle inhibitor is active.

The issue is either:

1. The application does not register an idle inhibitor correctly
2. Sway is not handling the inhibitor correctly

[wadeduvall]

Switching to sway did not resolve the issue. Issue also exists with hypridle. So in theory you could probably close this issue. BUT if you still want to help:

@kennylevinsen I did check, and mpv does inhibit properly, so I'm guessing it's not sway's fault. Do you know how to check if idle inhibit is set?

Okay, this is 100% not y'all's issue:

method call time=1715027322.089262 sender=:1.110 -> destination=:1.11 serial=47 path=/ScreenSaver; interface=org.freedesktop.ScreenSaver; member=Inhibit
   string "firefox"
   string "video-playing"
error time=1715027322.089362 sender=:1.11 -> destination=:1.110 error_name=org.freedesktop.DBus.Error.UnknownObject reply_serial=47
   string "Unknown object '/ScreenSaver'."

Closing.
