Perhaps 2048 hits a limit on your hardware and it falls back to software.
You don't need to scale up to a power of two for the capture though since
pix_snap2tex uses subtexturing or rectangle textures when available.  Even
at powers of two the 2048x768 is 2048x1024 which is the exact same number of
pixels as the two 1024x1024.
