Unable to resize window in XFCE with McOS-CTLina-XFCE

[spsf64]

When I select McOS-CTLina-XFCE or McOS-CTLina-XFCE-Dark in XFCE "Window Manager/Style" settings, I cannot resize windows if I try to "grab/select" it with mouse pointer from the sides, bottom or bottom corners, it only works when selecting the window from top or top corners.
Is this a feature or a bug?
TIA

That is a problem caused by the XFCE window manager.
