Resolved Issues

• 60Hz SST flickering has been identified as an issue with non-standard display timings exhibited by the AOC  U2868PQU panel on certain AMD Radeon™ graphics cards. A software workaround has been implemented in the AMD Catalyst 14.9 driver to resolve the display timing issues with this display
• Users seeing flickering issues in 60Hz SST mode are further encouraged to obtain newer display firmware from their monitor vendor that will resolve flickering at its origin. 
• Users are additionally advised to utilize DisplayPort-certified cables to ensure the integrity of the DisplayPort data connection.
• 4K panel flickering issues found on the AMD Radeon R9 290 Series and AMD Radeon HD 7800 Series
• Screen tearing observed on AMD CrossFire systems with Eyefinity portrait display configurations
• Instability issues for Grid Autosport when running in 2x1 or 1x2 Eyefinity configurations
