Slow window opening troubleshooting

This one?

Changed to debug, then started switching windows, but the only thing that shows up in the console is the print statements that I added to my window. Is there anything else I need to do to ‘apply’ the setting? Close the diagnostic window, then reopen?

Edit: I switched to one of the other windows and noticed a debug message for that one, so I guess the setting is working. It’s just that the window must not need to be decoded in this case (while it’s running slow). There’s no entry for that window when switching to it.
