Public bug reported:
QEMU version is 3.0.0
# Description
The problem is that, when typing string through VNC, it can be
unreliable -- sometimes some key strokes get skipped, sometimes get
swapped, sometimes get repeated. There's no problem when typing through
VNC on physical hardware.
# Steps to reproduce
1. Launch virtual machine by:
qemu-kvm -display vnc=:1 -m 2048 opensuse-leap-15.qcow2
2. Connect to VNC by:
vncviewer -Shared :5901
3. Simulate a series of key strokes by "vncdotool" [1]:
vncdotool -s 127.0.0.1::5901 typefile strings_to_be_typed.txt
4. Usually after a few hundred keys are typed, something goes wrong.
I attached a screenshot that it mistypes " hello" to "h ello".
