Just to ensure that this horse is totally beaten into the ground,
I think you should change the following lines to avoid the problem
of offscreen or obscured X-windows:

If you the following code snippet, you won't get garbage:

; Make the window current. Get contents.
window,/free,/PIXMAP,XSIZE=!d.x_size,YSIZE=!d.ysize ; create a temp
pixmap window
device,copy=[0,0,!d.x_size,!d.y_size,0,0,wid] ; transfer wid
contents
contents = tvrd(0,0,!d.x_size,!d.y_size) ; grab pixmap
contents -- no offscreen problem
; just for us old WAVE programmers, use ALL the tvrd parameters :-{
wdelete, !d.window ; delete the temp
pixmap window
wset, wid ; make the window
current
