Nope it is normal. The bevel border of the panel is part of its client
area. So it can be overridden by its child controls.

Ok. If bevel border area is in client area, this mean, right and
bottom bevel border area has to override by child controls, when
".Align := alClient" isn't it?
I'm in kubuntu and QT widget set

Yes all borders are overridden in the case of a non transparent
control like TBGRAVirtualScreen. If you want to avoid this, you can
set the coordinates to (1,1) and the size to
(ClientWidth-2,ClientHeight-2) and use all anchors.
