Intel video driver

The intel graphics driver can sometimes cause various window artifacts such as seemingly corrurpted text and screen tearing.  This can be caused by the default accleration method, called sna (sandy bridge new acceleration)

Though most scanners will work out of the box, there are occasionally problems that arise. This thread contains solutions that have been worked out for such problems.

I discovered this issue with MX15 and it's back in MX16 RC1. After using content from any external hard disk that I connected via USB, the drive is always busy, even 10 minutes after last use.
