Do you mean the main browser window or the popup opened when you click the Multi-Account Container icon?

The main window. In fact if you put the main window on 2nd monitor, the main window "flash" (show up) in first monitor first and then is sliding on the 2nd one (the last saved position). The main window must be created hidden until it is properly positioned.
