I have 3 monitors and after installing driver 15.7 if pc is idle for 10 minutes I get flickering horizontal lines at the top of all three monitors. Only a reboot would fix it and then it would come back after idle time. I rolled back to Omega drivers and all is well. Yesterday I install latest beta 15.8 in the hope this issue had been addressed but still occurring. However when I put any load on the GPU it goes away and immediately comes back when gpu is idle.
