Description
This was reported previously, but the ticket has been closed as too old with no resolution. Since VBox version 5.0 the full screen mode is unusable on Red Hat Enterprise Linux. If switched to full screen mode, the screen is not painted correctly showing either the host desktop (not the guest desktop), or the host desktop is overlaid over the guest desktop. Major issue that seems to be ignored by developers. The hardware is ThinkPad W520.

Which is the other ticket you are talking about?
Does this problem also happen if you disable "2D video acceleration" and "3D support" in your VM settings?

I'm sorry, I should have double checked. Most of my tickets were closed as too old. I've got bunch of emails regarding that and stating to open a new ticket if the issue is still present. However, that one wasn't closed. It's number is 14637.
Anyway, 2D acceleration is checked, but it's greyed out, so I can't uncheck it. 3D acceleration is not checked. The video driver is the one for Intel graphics (nouveau or something like that), not nVidia.

The checked but disabled "2D video acceleration" is weird and sounds like a bug. Please could you do the following:
- Make sure that no VM is running and that the VM selector is not open
- Make sure that VBoxSVC is not running, perhaps wait for 10 seconds.
- Manually edit the VM settings file and look for the 'accelerate2DVideo' key. Replace 'true' with 'false'
- Save the settings file and restart the VM.
Any change / improvement?

Actually: Are you 100% sure that 2D video acceleration cannot be disabled when the VM is powered-off?

Yes, I'm positive. I wouldn't do that simple mistake, however I double checked again today. It was disabled and greyed out when VM was not running. I have another VM that I rarely boot. It had the same thing (2D acceleration checked and greyed out). I rebooted the laptop and the setting was still disabled (greyed out). I edited the config file manually as you suggested, saved it and opened VM settings. Guess what? Even though the setting is set to false it is checked and greyed out in the GUI. And that change didn't make any difference. The full screen mode is still unusable.

Just to double-check: When you changed the VM setting in the .vbox file there was no VBoxSVC service running, correct?

Sorry for the delay. Had a very busy time for the last few weeks. Anyway, this a Linux machine. The service stops after the last VM is closed, right? If so, the service shouldn't have been running. I never had any issue updating any settings for the VM that wasn't running. This was the first time that something was disabled for a closed VM.
