Created attachment 171248 [details] Round corners under titlebar - transmission-gtk and handbrake See attached image for more info. Operating System: Manjaro Linux KDE Plasma Version: 6.1.1 KDE Frameworks Version: 6.3.0 Qt Version: 6.7.2 Kernel Version: 6.9.7-1-MANJARO (64-bit) Graphics Platform: Wayland
This is almost certainly a GTK issue, as the content affected by the rounded corners is drawn by GTK, not us. I'd guess it's assuming CSDs rather than SSDs and not handling that latter case correctly. Please report this to the GTK devs.
My mistake, this is indeed our styling bug.
