Having a issue with ghost instances of apps in alt-tab after last update i believe using DisplayFusion Pro on Steam 9.0 on Windows 10 (also up2date).

Apps include command windows, settings window from a few other apps, and also tons of firefox 57 processes (assuming it has something to do with multiprocess of firefox, and it firing/closing them, not sure, also not in picture)

Might a similar bug to this thread had ?

Thanks this fixed it, i thought i was up2date, since usually DF says when its time to update =)
