Seamless mode issue on Fedora 27 MATE desktop

[Zhijian]

Hi everyone,

I have installed virtualbox 5.2.4 on Fedora 27 MATE desktop.
But the seamless mode doesn't work.
When I turn on the seamless mode, it displays nothing.
Other modes (full-screen and scaled mode) work normally.
Could anyone kindly help me to solve this problem?
Thank you.

The guest os is Windows XP.
However, this issue is still found after switching to the guest os Fedora 21 MATE desktop.

Here is some of the log:

Fedora 27 does not seem to be a supported host OS. Where did you download it from?

In fact, please provide the complete VM log as a zipped attachment.

I added the vbox repo file into the repo configuration path "/etc/yum.repos.d/" of Fedora desktop following the instructions on the download page:

https://www.virtualbox.org/wiki/Linux_Downloads

Then I can install it via dnf command.
Of course, this package seems to be developed for Fedora 26.

Installed Packages
VirtualBox-5.2.x86_64 5.2.4_119785_fedora26-1 @virtualbox

However it works on Fedora 27 too.

Okay, here is the tarball that contains the complete log files.
