[Bug 1802465] Re: typing string via VNC is unreliable

[Thomas Huth]

The QEMU project is currently considering to move its bug tracking to
another system. For this we need to know which bugs are still valid
and which could be closed already. Thus we are setting older bugs to
"Incomplete" now.

If you still think this bug report here is valid, then please switch
the state back to "New" within the next 60 days, otherwise this report
will be marked as "Expired". Or please mark it as "Fix Released" if
the problem has been solved with a newer version of QEMU already.

Thank you and sorry for the inconvenience.

Title:
  typing string via VNC is unreliable

Status in QEMU:
  Incomplete

Bug description:
  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".
