Sometimes when I am in a pop and someone is sharing their screen, if I click the button to make everyone's videos go full screen (the button in the first screenshot), the pop window will sometimes break. The videos of the people in the call try to become full size but the pop window itself will stay small. The window of the screen share stays the same. The second screenshot shows what happens when I click the full screen button. I cannot resize the window to try and put everything back to normal. I have to quit the Pop application and open it again.
