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. https://bugzilla.redhat.com/show_bug.cgi?id=865767 Signed-off-by: Gerd Hoffmann (cherry picked from commit e32c25b5f2452c7fed4dbe8962f4a9f4831fbe24) Conflicts: hw/qxl.c --- hw/qxl.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-) Signed-off-by: Michal Novotny --- hw/qxl.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/hw/qxl.c b/hw/qxl.c index 04f9dd8..074b0eb 100644 --- a/hw/qxl.c +++ b/hw/qxl.c @@ -1010,7 +1010,7 @@ static void qxl_enter_vga_mode(PCIQXLDevice *d) trace_qxl_enter_vga_mode(d->id); qemu_spice_create_host_primary(&d->ssd); d->mode = QXL_MODE_VGA; - memset(&d->ssd.dirty, 0, sizeof(d->ssd.dirty)); + dpy_resize(d->ssd.ds); } static void qxl_exit_vga_mode(PCIQXLDevice *d) -- 1.7.11.7
