I've been on beta for 6 for a while and was all working and looking fine but at some point over the last day or so it has become completely broken and unusable. Something has gone badly wrong with scaling. (see attached image)
Alignment is wrong, UI is out of place and text is low res and blocky. This has only just started happening, was all fine yesterday and before that. I have tried uninstalling, reinstalling, rebooting etc. My machine is a Dell XPS 13 (9370) laptop with 4K screen.
