    Description

      When multiple screens are connected to a Mac, we see high CPU consumption by the Qt app (and the Qt app becomes less responsive) when a Qt app window is positioned on a secondary screen.

      This does not happen if the Qt app windows are on the main screen.

      The attachments contain sampling results for the two conditions.
