For some reason, ST3  window is flickering when the computer (with a ST3 active session) is waken up. It does not always occur, I would say every other time. This is especially visible on an external HMDI 4K display or on the mac screen when it wakes up unplugged and ST3 used to be displayed on the external screen.
Resizing ST3 main window usually stops the flickering.
Any idea why ?
