BertN45, thanks for the clarification.
Given Oracle upstream has indicated on their website the root cause of this
issue is due to their Guest Additions version, and the fix is to upgrade only
the Guest Additions version, I'll reassign to virtualbox for review:
1) Agreed, I will file another bug report.
2) I did already provide that information to you in the original bug-
report using Vbox Guest Additions (VGA) 5.2.4. It did take a lot of time
to produce it, because the system took 10-60 seconds to react to any
mouse click.
Remember the problem occurs

One month ago I upgraded Virtualbox from 5.2.4 to 5.2.6. While I was upgrading
Vbox Guest Additions in my VMs to 5.2.6, I detected that that 5.2.6 Guest
additions introduced a serious boot/login problem for all my VMs. So as a
work-around I kept all my VMs at Guest Additions 5.2.4. I

To clarify, using a host with 5.2.6, if you use the Oracle guest
additions from version 5.2.4 this problem is not reproducible in Ubuntu
GNOME?

issue during login. The beta version 5.2.7 did solve the 5.2.6 login
issues.

the potential difficulty in solving a bug has no impact on Importance.

For me the problem is kind of important, since I moved all my work to
specialised Virtual Machines;
