[Bugfix] Copy current lcd contents into empty background buffers

the manual states the following:
%V(0,0,-,-,-) %VB
Use %x(filename, 0, 0) to draw a backdrop image (If you want one!)
Then add %V(0,0,-,-,-)

if you forget then it causes display corruption
due to the uninitialized background buffer

instead make a copy of the current screen into the blank backdrop
so we won't be showing garbled data on the screen
