When I do actions in the 4.10 Mac Editor that cause the editor to display a popup dialog, the editor can become unresponsive and the popup cannot be focused. I’ve also noticed it happens if multiple dialogs are on top of one another. In one example I selected “Submit to Source Control”, and the editor spawns two popups, one appearing to be a message, and the other a progress display. However, the two popups are immediately unfocused (hidden, even when the editor is minimized). If I switch active desktops, I can see the two popups appear briefly, but they disappear in under a second, so I’m unable to click them. At this point, the editor’s menus are responsive, but the UI is not. However, when I select “Quit”, the editor does nothing.
EDIT: Here is a screenshot of the issue. It was taken in the <1s time period that the dialogs were on screen. Also, this issue might be related.
