[Qemu-devel] Crash when booting KDE Neon using qxl-vga |

With QEMU version 3.1.50 (v3.1.0-1218-gad7a21e812-dirty) (commit
ad7a21e81231ae64540310384fb0f87ac8758b02) on Xubuntu 18.04 host, a KDE
Neon guest is crashing on boot. The QEMU command line is:
gdb -q -ex "set pagination off" -ex "set print thread-events off" -ex
"handle SIGUSR1 nostop nopass noprint" -ex "run" --args
qemu-system-x86_64 -accel kvm -cpu host -smp cores=2,threads=1 -m 2048
-hda neonbroken.qcow2 -cdrom
~/Downloads/neon-useredition-20190124-0530-amd64.iso -device
qxl-vga,xres=1366,yres=768,addr=2 -display gtk,gl=on -monitor vc -serial
vc -device qemu-xhci,addr=3 -netdev user,id=net0 -device
e1000,netdev=net0,addr=4 -bios /usr/share/ovmf/OVMF.fd
The crash is happening pretty frequently but not 100% of the times.
Using virtio-vga instead of qxl-vga it's possible to use the guest
normally. Before the crash there are some graphical artifacts on guest
screen, they can be seen at https://i.imgur.com/rfTmmJ0.png
On terminal QEMU prints the following messages:
$ qemu-system-x86_64 -accel kvm -cpu host -smp cores=2,threads=1 -m 2048
-hda neonbroken.qcow2 -cdrom
