Installing Mint on Virtual Box will give this video error. Getting rid of it is easy but maddening to find. I have always just lived with it but decided to finally hunt down the fix.
Then open the guest additions CD through "Devices" in the menu. The CD will appear on the desktop. If you double click the CD you will see the contents.
Now in Terminal cd /media/user/ to that folder and perform the run command.
Then go to "Display" in settings and check "Enable 3D Acceleration. I believe you will need Mint shut down to change this setting. You can see the setting with Mint running but it is grayed out. This step is left out of the instructions I found on line.
Rebooting should now remove the error.
