Description Nate Graham 2020-06-06 19:53:30 UTC 
OpenSUSE Tumbleweed with Qt 5.15 and all KDE software built from today's git master.

STEPS TO REPRODUCE
1. Set scale factor to 200%
2. Reboot
3. Open any app with server-side decorations (i.e. a KWin-drawn titlebar)

OBSERVED RESULT
The corner radius of the top corners is not scaled with the scale factor, so it is very small and the window looks almost square.

EXPECTED RESULT
The corner radius is is exactly the same physical size at 200% scale on a 4k screen as it would be at 100% scale on an FHD screen.
