White Edges around Buttons

[timbiermann1271]

Just started playing around with Visual Studios 2022 and Material Skin. I am having an issue when I place a button, basically there seems to be a white edge that is visible around the edges as shown in the picture below.

I am using Framework 4.8

Any idea what is causing this?

Many Thanks

I found that shadow causes undesired coloring in the corners. I had to remove the code:

DrawHelper.DrawSquareShadow(g, ClientRectangle);

for the button to get rid of this.
