adwaita-qt: dark theme for Qt applications doesn’t work on NixOS 20.09 #98009
Description
It used to work before 20.09 on nixos-unstable channel.
Here https://github.com/unclechu/nixos-config/blob/41e8bc34a12d018f645cfabcd892cab381e583c1/configuration.nix#L144-L148 I’m setting Qt theme:
qt5 = {
enable = true;
platformTheme = "gnome";
style = "adwaita-dark";
};If I for instance run vlc I see this error message telling me that adwaita-dark is an incorrect style value:
VLC media player 3.0.11.1 Vetinari (revision 3.0.11.1-0-g52483f3ca2)
[0000000000649610] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
QApplication: invalid style override 'adwaita-dark' passed, ignoring it.
Available styles: Windows, Fusion
Same story for other apps like smplayer, audacious and psi-plus.
