If you've been experiencing the AMD watermark issue with the 8.39.4 Linux driver, there is an unofficial workaround to correct this problem. As is outlined in this Phoronix Forums post, you can obtain the signature value from the ATI/AMD driver package and then manually place it in /etc/ati/signature to remove the "testing use only" watermark. This is not the official workaround sanctioned by AMD and the 8.39.4 fglrx driver was removed from the AMD website earlier today. Find out more in the Phoronix Forums.
