Hello,
I have found a bug/issue of Gnome apps that have a search filter or search predictive typing results. When the window of the app is in the upper left hand corner of the screen it is located on the results show fine but when not the results show up on another screen. I do not believe it is expected behavior. I tried to add screenshots but when I attempted to post it, a message stated embedding media was not allowed.
Has anyone run into this before? Let me know what further information or details you would like. Thanks.
