When a new Immediate Viewport is opened and the program is minimized,
the new Immediate Viewport remains displayed on the screen but becomes unresponsive.
When the program is restored from the minimized state, the Immediate Viewport starts functioning again.

This issue occurs after a recent update.
In previous versions, the new Immediate Viewport was not displayed on the screen when the program was minimized.
