Subject: [PATCH] qxl: call dpy_gfx_resize when entering vga mode
|
|
|
|
When entering vga mode the display size likely changes,
|
|
notify all displaychangelisteners about this.
|
|
|
|
Probably went unnoticed for a while as one if the first
|
|
things the guest does after leaving qxl native mode and
|
|
entering qxl vga mode is to set the vga video mode. But
|
|
there is still a small window where qemu can operate on
|
|
stale data, leading to crashes now and then.
