xmonad has no direct control over what is drawn to the screen, only over  
higher level operations such as window position/size and what windows are  
mapped. This kind of drawing artifact usually indicates that the video  
driver has bugs related to server-side window borders, which are rendered  
directly by the xorg video driver based on server window properties  
(border_width, border_pixel, border_pixmap; see XChangeWindowAttributes()).

These bugs are not at all uncommon in NVidia drivers, as they are generally  
only tested with reparenting window managers that use frame windows instead  
of server-side borders.
