I actually meant GTK Apps on KDE Plasma. Like this... I just tested KDE in a VM and installed some Flatpaks and it just looks weird ... is there a way to fix this? Or how do you guys manage to make KDE Theming consistent with Flatpaks?
As far as I know there is a way to change the colours of GTK apps, but as for the titlebar/the general look of the app they're always going to look out of place
