[vbox-dev] Seamless mode is broken on 5.2.x (X11 guest on X11 host)

[Hans de Goede]

Hi All,

It seems that seamless mode is broken when using 5.2.x as a host,
I've tested this with both 5.2.2 host + guest as well as
with a 5.2.4 host + guest.

This is with the official vbox host RPM packages on top of F27
x86_64 running a GNOME3 session in Xorg mode, with a F27
x86_64 guest also running a GNOME3 session in Xorg mode.

There are 2 problems:
-1 the coordinates seem to be off, see e.g. :
  https://fedorapeople.org/~jwrdegoede/Screenshot%20from%202018-01-15%2016-24-45.png
-The window does not refresh if I type something in the
  terminal then it does not show, until I leave seamless
  mode again.

Both problems go away if I downgrade the host to 5.1.30,
while keeping the guest-additions at 5.2.2 (not tested
with 5.2.4).

Regards,

Hans
