100% CPU usage when launched with rofi-twitchy

I am getting 100% CPU usage on a single core when launching a stream from the rofi-twitchy plugin. When launching a stream from cli via twitchy or 'mpv ', I'm only seeing around 10% usage. I've also tried enabling hardware acceleration but get the same results.

This occurs with either mpv or vlc when set in the config.

I am able to reproduce this on two machines both with arch/intel cpu's.

From rofi:
with_rofi
Without:
without_rofi

OS: Arch
Kernal: 5.3.10
Nvidia Drivers: 440.31
CPU: Intel i7-4790k

I can think of the following:

  1. The launch from rofi is overriding hardware acceleration. If the relevant setting is enabled in ~/.config/twitchy3/twitchy.cfg, I would recommend checking out default launch flags for mpv in the config file.

  2. Change rofi to run twitchy with --hanselgretel. This will terminate twitchy after launching the video. In case the issue is script specific, this should fix it.

Sorry for the delay. Streamlink is currently giving me the "410 Client Error (Gone for url) #2680" issue so I'm not able to test right now.

I did however try enabling and disabling hardware acceleration in the twitchy config and mpv/vlc configs prior to opening this issue but the problem was there in any case when launching from rofi.

I'll try your second suggestion when streamlink gets sorted again. Do I just add the --hanselgretel flag like so?
rofi -modi twitchy:rofi-twitchy -show twitchy --hanselgretel

Thank you.
