playerctl play-pause lag

[Roman-]

When trying to control musikcube with playerctl, the play-pause command always been executed with a ~0.7s delay:

$ time playerctl --player=musikcube play-pause
playerctl --player=musikcube play-pause  0,01s user 0,00s system 0% cpu 0,923 total
$ time playerctl --player=musikcube play-pause
playerctl --player=musikcube play-pause  0,00s user 0,00s system 0% cpu 0,670 total
$ time playerctl --player=musikcube play-pause
playerctl --player=musikcube play-pause  0,00s user 0,01s system 0% cpu 0,670 total
$ time playerctl --player=musikcube play-pause
playerctl --player=musikcube play-pause  0,01s user 0,00s system 0% cpu 0,746 total
$ time playerctl --player=musikcube play-pause
playerctl --player=musikcube play-pause  0,00s user 0,00s system 0% cpu 0,598 total

Doing play/pause with musikcube interface (spacebar) executes instantly, no pauses. Playerctl on other players also work instantly.

Anyone experience same issue? playerctl v2.4.1, musikcube 0.98.1

Same issue here, using playerctl with any other app takes ~10ms, but musikcube has a ~0.7s delay. Using dbus-send directly is faster, but still seems to vary between ~25ms to ~0.5s:

Also experiencing on KDE, slow response when using Multimedia keys, especially changing volume. No issues with other apps. Has anyone found a fix?
