I don't use mission control, but I'm able to have the bigger window stay open while I click in the window I'm sharing, and also click in other unrelated windows I'm not sharing.

Not sure why it's different for me and you, but I'm not shocked, the software is definitely a mess.

But I somehow don't have the particular problem you are having... anymore.

It seems to be an issue when something covers part of the Teams window. I have the same issue as the parent poster.

If a window is placed over top of the Teams window with all the floating faces, it minimizes itself into that small window...
