Here is the picture that shows the problem. Take a look at the bottom right corner.
Anyone knows how to get rid of it?
Setting LayoutStyle to VerticalStackWithOverflow fixes it but also centers the items horizontally which I don’t want.
I just want a vertical stack like in the pic, but without that black line in the bottom right corner.

In the properties bar, set “RenderMode” to “System” or use
Doing this will change the .BackColor to “Control” but you can change that after if you want.
