I noticed some flickering and texture errors in Blizzards game "Overwatch".
After some experimenting i found out that this error results from the installation of the latest Crimson drivers.
After going back to driver version 15.12 all graphics errors stopped appearing.
AMD A10-7850K APU
8GB AMD Radeon Gamer Series RAM DDR3
CPU clock: 3,7 GHz / 3,0 GHz; GPU clock: 900 MHz, RAM: 2400 MHz
Error also occurs on lower clockings; also occurs on lowest detail settings ingame.
No heat problems.
