ui/spice-display.c uses ds_mirror to figure which screen areas did actually change. This is active when the qxl card is in vga mode or a non-qxl gfx card is used. A display resize invalidates ds_mirror, and it is handled by simply simply freeing ds_mirror. The next screen update it will be re-allocated as needed. With qxl there is another possible code path which can invalidate ds_mirror: leave vga mode and re-enter vga mode. Make sure we free ds_mirror here too. https://bugzilla.redhat.com/show_bug.cgi?id=865767 Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> --- hw/qxl.c | 2 ++ 1 files changed, 2 insertions(+), 0 deletions(-)
