Comment 3 for bug 391340

ok,
i can reproduce it now from the start:

Import A
scale A to 10 %
import B
scale B to 10 %
Move the molecule of A into the white space around the molecule of B
clip away the white space around B
clip away the white space around A

expected result: both A and B should be sharp

actual result: A is blurred and B is partly blurred.

File A and B were generated with pymol.
