First Viewport Not Displaying When Programmatically Creating Multiple Viewports

I'm experiencing an issue when programmatically creating viewports in AutoCAD. Using this workflow:

Create multiple layouts and add viewports (without switching to layouts)
Later switch to each layout, erase default viewport, and turn on custom viewports

The first viewport in each layout doesn't display content while all subsequent viewports work fine. The problematic first viewport appears at a random position and can't be modified or selected with QSelect.

It looks like you're erasing the paper space viewport. This is not a floating viewport, it represents the entire layout view and you can't see its border.
