Created attachment 185852 [details] no GTK app buttons video I use breeze, after recent update to plasma 6.4.5 i noticed GTK apps have no buttons see attached screencast with firefox and kde app side by side
i think the issue was related with opensuse slowroll missing libglycin-gtk4-2-0 or glycin-loaders when launching Remmina i got the error message that those might be missing, I installed it and then the buttons reappeared for Firefox
