Hey guys, any help would be appreciated on this as I’ve been banging my head against the wall for days. I use Picard to tag audo files with the correct metadata. It is from my understanding a QT application, but on my Gentoo install it pulls in my GTK theme. On NixOS, with virtually the same WM, shell, theme and environment variables, the application does not respect my GTK theme and opens in a blindingly white window (seriously one of the whitest whites you’ll ever see). It does not have a “dark” mode and relies on the systems theme.
I have a very small amount of environment variables set on both devices, mostly to make niri and gtk work correctly. To my knowledge I did not configure anything different on Gentoo, but when I do env | grep -E 'QT_' I see:
QT_QPA_PLATFORMTHEME=gtk3 (I set this for niri)
QT_STYLE_OVERRIDE=Fusion
QT_QUICK_CONTROLS_STYLE=Material
I tried to replicate this on both the system level and user level on NixOS with environment.variables = <variables> and through home.sessionVariables = <variables>, but no dice. I thought maybe it’s because of missing qt libraries, which I added with pkgs.libsForQt5.qtbase & libsForQt5.qtstyleplugins which did not resolve the issue. When I run picard and grep the relevant variables, I do see that they now match gentoo’s, but its still white. I also found that Picard thought my theme was Adwaita, which doesn’t make any sense because I haven’t set Adwaita as a theme anywhere. All of my GTK apps respect my theme. If I need to wrap picard with a dark theme I guess I can do that but feel like theres something I’m missing here.
