After all, imho, I derived the formula for the window stuck problem:
XBINDKEYS, X11, ?WAYLAND!, ?QT?, ?GTK?, !your_WindowManager, VirtualBox.

Good question:) Yep, xbindkeys is too far from VirtualBox...
I am install fresh Xubuntu18.04, VBox windows move ok.
After installing some packages and add some configs - VBox windows stuck.
Found this forum thread - no solution. I assumed that I am closer to the bug than others.
Then just reinstall fresh Xubuntu18.04 and repeat my log step by step.
Bingo! After customize ".xbindkeysrc" - VBox windows stuck again.
So, "it's" near the xbindkeys. Publish investigation results.
I spent several hours, but I hope this will save a lot of time and nerves for the world.

Two ideas for you:
1) "How to disable Wayland and enable Xorg display server on Ubuntu 18.04 Bionic Beaver Linux"
https://linuxconfig.org/how-to-disable- ... aver-linux
2) Also you can try Compiz with Wayland enabled and/or without it.
To enable window decorations "borders or controls" in Compiz:
Install Compiz WITH PLUGINS: $
sudo apt-get install compiz compiz-plugins compizconfig-settings-manager
run "CompizConfig Settings Manager": $ ccsm
enable
plugin "
Window Decoration" in "Effects" section,
enable
plugins "
Move Window" and "
Resize Window" in "Window Management" section.
?enable plugins "Composite", "Gnome Compatibility" and "OpenGL" in "General" section
start compiz: $
compiz --replace
...to revert back to your previous WindowManager simple
reboot or : $ YOUR_WINDOW_MANAGER --replace
P.S. Maybe related info:
1) "Due to a mistake, Qt Wayland was made the default platform plugin on gnome-shell sessions in Qt 5.11.
The combination of gnome-shell and Qt Wayland still results in too many bugs,
and hence Qt Wayland was removed from the Qt Creator pre-release builds altogether,
at least until Qt Wayland is made opt-in again."
