Icons get squished in the Auto Options Menu of a TAdvToolBar

When at 100% Windows display scaling, the icons shown in the auto options menu pop up to show/hide various toolbar buttons are fine, but at higher display scaling they get squished horizontally. I am using a virtual image list for the toolbar buttons.

At 100 % they look good:

But at 200% they are squished horizontally:
