Mouse cannot click on guest. Keyboard working fine

[SilencioU]

Hi, i just upgrade my host fedora 19 to fedora 28.
In fedora 19 everything was working fine, but with the upgrade, virtualbox is making trouble.

I ran virtualbox 6, if im not in full screen then it works perfectly for several hours, but the mouse "crashes" randomly.
If i start virtualbox in full screen or i change from another visual format to full screen, the mouse crashes in minutes.

This is the problem: The mouse works bucause im able to move into the guest and the host, but i cannot click anything inside the host (windows xp). If i use the keyboard im able to navigate and keyboard-click wherever i want, but the mouse cant.

Someone has a solution? or the same problem?

Open a Terminal, and with no VM running, type the command:

• 
  VBoxBugReport "<VMname>"

where "<VMname>" is the actual name of the VM that you have a problem with. This will generate a "YYYY-MM-DD-hh-mm-ss-bugreport.tgz" file in the current directory (most probably your home directory). Attach that file in your response.
