Both external and laptop screen are 1920x1080. They are driven by a NVIDIA RTX 3050 card with the proprietary NVIDIA drivers.
KDE is running on X11 still. As a matter of interest I opened up a GNOME session on Wayland. The results are the same. The demo project compiles and runs on GTK2 but not on QT5.
Is there a changelog for libQt5Pas anywhere?
