Extra space in Start menu
I have a new (to me) Dell XPS 13 9360 laptop, with a fresh install of Windows 10, version 2004. I installed Start 10, and it gives me excess space on both sides of the start menu.

In addition, the normal Start button I replace the default with shows up very tiny. I had to expand the PNG to 250x normal size to get it to display properly.
The display resolution for this screen is 3200x1800.
Any assistance would be appreciated.
