Custom scheme and flatpak apps

KDE Neon / Plasma version 6.5.2

I have a custom window-header color selected in a custom color scheme. (system settings, appearance and style, colors). None of the dozen or so flatpak apps I have installed follow that scheme. Is there anyway to fix that?

Have you tried Flatseal to allow all applications access to system files?

Yes, tried it on a few of the flatpak apps (kdenlive, and chromium), and it didn’t change anything.

Have you tried forcing the titlebar colors? On titlebar alt+F3, more actions>special…(or using system settings, window rules)

Yea, thanks, that works (by forcing the title bar scheme). But it seems I have to do this for each flatpak app?

This method? I’m afraid so.

Thanks, this does help with the few flatpaks I use a lot. Some don’t use a system title bar anyway.

Well, the advantage is that you can use certain schemes for certain apps. Mind you, depending on the window decorator, some additional stuff for specific apps have to be set. For example, I use Klassy. But in order to have, say, opaque decs, it has to be set in the window specific settings.
