Hi Dave.
This is a known issue with High DPI displays. I have the same issue on my Microsoft Surface 6. The issue is because by default your Windows scaling is probably set to something like 200%. If you change it to 100% everything will be displayed correctly ‘but’ it will probably be very small!
One workaround is to set the environment variable QT_AUTO_SCREEN_SCALE_FACTOR to 1
Eventually we will make wfview High DPI aware and it should be able to resize areas of the screen to account for this but the workarounds above should work in the interim.
