Hi have ATI Radeon 4570 card and random white lines come all over the screen. This problem began when i upgraded from Kernel 3.13 on linux mint and no matter what distribution i installed (Kernel 3.16, 3.16, 4.4, 4.9) the problem remained. Finally set radeon.dpm=0 and the problem is gone. Would like to get this resolved. Please let me know which files to attach.
