Areas of the Welcome screen are not displaying (FrameMaker 2019)

The Welcome screen is not adapting to a larger screen and is just missing (grayed out) at the bottom and side.

I can zoom in and out like normal to view the content, but this makes no changes to the missing areas. Changing the window size also makes no difference.

I think this is the same as the feed below but there is no solution.

Does one know why this is happening?
