Operating system, environment and configuration details

ArchLinux running Gnome in dark mode.

Description

When using the default "System settings" as a theme, despite Gnome using the Dark style, Streamlink Twitch GUI keeps using light there.

From a few things I saw in another issue, this might also be an upstream problem though.

I didn't checked other desktop environments, which might also encounter such issues.
