--- Comment #14 from Clésio Luiz <magolobel at yahoo.com.br> --- I tested now with 2 displays, the Benq monitor (DVI cable) at 120Hz and a Lg TV (HDMI cable) and the glitches disappear. When I disable the TV (from System Settings) and disconnect the cable, the glitches are still gone. Only when I restart the system the glitches come back. I should mention that any refresh rate above 60Hz triggers the problem, not only 120Hz. -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
