Mouse intigration issues impacting guest and hsot VM Manager app

[jacksquat]

Very first click in guest VMs always works, but shortly after:

• clicking fails in guest AND host VB Manager application
• guest cursor fails to move

This issue began when updating to Version 6.0.14 r133895 (Qt5.6.1).

Issue replicated on:

• Host: Fedora release 31 (Thirty One) (uname: Linux localhost.localdomain 5.3.16-300.fc31.x86_64 #1 SMP Fri Dec 13 17:59:04 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux)
  • Guest: Fedora release 31 (Thirty One) fully updated - with reinstall of guest additions (log file attached)
  • Guest: Win 10 fully updated - with reinstall of guest additions

VB log file attached. Any input appreciated. Grep of log for "Mouse" below with shutdown request at time stamp 00:02:23.010432
