      Description

      When a large window is dragged, the operation is sluggish.

      I've profiled the compositor's frame() method and it is clear that the format conversion for the non-client area image is taking a lot of time (qopengltexture.cpp:3643, image.convertToFormat)

      This is radically sped up if the image already has the requested format.
