Heh, we added OnScreenDisplay as a type and this code isn't updated. Almost certainly that. Will fix.
Git commit 2693e288c57a66facbe6b9932ce8628a53afb246 by David Edmundson. Committed on 27/06/2018 at 00:36. Pushed by davidedmundson into branch 'Plasma/5.13'. Avoid potential assert in SM saving Summary: Sesison Manager stores all relevant clients. There's an assert if the window type is outside of the standard client window types. It assumed that all windows outside this would be Unmanaged windows rather than Client objects, something probably true but not something enforced. This particular crash was probably cased as we have a new window type in Plasma OSD, which does not set BypassWindowManager in Qt window flags.
