Did you https://wiki.archlinux.org/title/GTK#Hide_CSD_buttons ?
Did you disable SSD in the kwin settings?

Re: GTK apps on KDE wayland lost minimize and maximize buttons

Same issue here. It started since updating to GTK 4.20.x.
Not only are the minimize and maximize buttons missing in GTK4 apps, but setting a font in ~/.config/gtk-4.0/settings.ini with gtk-font-name is now also ignored.
Fonts before (right) and after (left) 4.20: Screenshot of mission-center showing font issue.
And in Pinta some icons in the titlebar are also broken: Screenshot of Pinta showing issues with titlebar.

I did neither. I think it might be ignoring

gtk-decoration-layout=icon:minimize,maximize,close

in settings.ini since GTK4-4.20 for some reason.

It's still reading the settings.ini file, because when starting a GTK4 app, journal shows:

Unknown key gtk-modules in /home/bb10/.config/gtk-4.0/settings.ini

when

gtk-modules=window-decorations-gtk-module:colorreload-gtk-module

is not commented out in settings.ini. I don't think it has to do with this issue.

And further:

/usr/lib/xdg-desktop-portal	A backend call failed: No such method 'CreateMonitor' in interface 'org.freedesktop.impl.portal.Inhibit' at object path '/org/freedesktop/portal/desktop' (signature 'ooss')

GTK4 grabs these from the xdg-desktop-portal implementation and xdg-desktop-portal-gtk was added as an opt depends for this reason, is that installed?

Yes, I've been keeping an eye on the gitlab issues on both gtk4 and kde-gtk-config. Unfortunately it didn't fix these issues.

Re: GTK apps on KDE wayland lost minimize and maximize buttons

Seems it is this bug: https://gitlab.gnome.org/GNOME/gtk/-/issues/7821

Tested mission-center with

GDK_DEBUG=no-portals missioncenter

and it's working fine again.
