[Spice-devel] Why 'draw-copy' operation in spice client will introduce many images for IE browser?

[xuzhinong999]

Hi, All,
   I am trying spice 0.6.3 now, spice client run on linux and qemu/spiceServer run on linux as well, and the guest OS is windows XP with qxl driver installed.
 
  spice client can start up correctly, but it will consume too much memory when launch a browser (Window IE 7.0). The web page is a little complicated with many text/image, the website ishttp://www.sohu.com. I found spice client will consume more than 120MB memory when i only startup the web page.
 
  I have done some debugging and has some result. It's very strange that the bbox->left & right means the absolute x-coordinate and y-coordinate of the image to be executed 'draw-copy' is 303, 304 , 305, 306, 307, etc, why these images are aligned so densely? I don't find there are so many images on the webpage in that area.
And the width/height is 450/105, but why 'GlzDecodeSurfaceHandler.alloc_image.width : 1280,  height: 556' say the width/height is 1280/556. Does the image be compressed and extracted on the webpage?
 
  I know some about the qxl driver and windows xp graphic processing. But i can't explain the above information. Can someone kindly give me a hint. Thanks.

The debugging result is as following:
