Incorrect screen width when is in full screen mode and spited.

1. Make the virtual box as full screen.
2. Make another application as full screen.
3. Join the virtual box and the application in mission control.
4. The virtual box takes only the half of the screen physically, but behave like the whole screen is given to it.

The right side of the picture is the virtua box, which behaves like it has the full width of the physical screen.

Typo in Title: spited -> splited

I posted the following comment in #18970 before I realized it was a duplicate of this one. Sorry for the repeated message...

It's usually better and faster, if issues get first addressed in the ​VirtualBox forums, a lot more eyes there. More than 95% of the issues are resolved in the forums, which keeps the developers focusing on the bug fixes and enhancements, and there is no need for another ticket to keep track of.

3. Join the virtual box and the application in mission control.

What does that even mean? Join how? Can you please explain it with some more details?

BTW, what's your OSX version, didn't mention that. And your guest?

You were supposed to follow these steps when you filed the bug, and provide a VBox.log:

Attach a (full) log file ("Machine" menu/"Show Log" in the main VirtualBox Manager window) straight away to save time for you and for us. The log file contains a lot of useful information about both the host and the guest systems as well as information about what happened during a particular machine run. Please do not cut and paste it.

No VBox.log and no follow up, closing as invalid. Please reopen if still an issue with the most recent VirtualBox release and attach the requested files.
