[Spice-devel] spice update_area and handle_dev_update_async

[feihu929 at sina.com]

In Windows or Linux guest os with qxl video card,  when some window, button or label  call frequently update, the remote spice client will display  error background . The window, button or label will draw background with the desktop image.Start the qemu with SPICE_DEBUG_LEVEL,  the vm log show large number  update_area and handle_dev_update_async function called.It seems that the update_area and handle_dev_update_async funciton has some problem, maybe about async display or surface canvas draw error?
For example , i am run matlab 2010 or matab 2012 in redhat 6.5 guest os , when open toolboxes Curve Fitting -> Spline Tool , the problem will happen.  the attachment  is the error screenshot image.
