[Spice-devel] 答复: spice update_area and handle_dev_update_async

[陈刚]

Hello, Christophe
The host os is redhat 7, qemu and spice is installed with redhat image.  The
QXL driver is too installed with guest os redhat 6.5.
I just encountered the problem with matlab, maybe other applications not
trigger the update_area fuction?
