@ -91,6 +95,21 @@ Discord. Basically: a virtual microphone is created which captures the
application audio, and this microphone is then fed to the Discord stream by
intercepting a API call of Discord.
### Drag and drop doesn't work in the Flatpak
This is due to sandboxing limitations of Flatpak. The main Discord Flatpak has
the same problem. If you still want to use drag and drop, you can disable most
of Flatpak's sandboxing by installing
[Flatseal](https://flathub.org/apps/details/com.github.tchx84.Flatseal) and
allowing access to "All system files" under the "Filesystem" section.
### Is there any way to add custom CSS / a theme?
Yes, you can add all your styles into
`~/.config/discord-screenaudio/userstyles.css`. But please note that due to
QtWebEngine limitations concerning content security policies, you can't use any
external files (like `@import` or `url()`).
