https://bugs.freedesktop.org/show_bug.cgi?id=93826 --- Comment #22 from untoreh --- I have a 290, monitor benq xl2411t. Pushing high resolutions both in grub or xorg file produces glitches. They are very noticeable at 120/144hz less noticeable at 100hz but still present. They appear if I set `video=1920x1080@120` option at boot time, or add a modeline with cvt in a xorg .conf file. However if I remove the modelines from the conf file and just do a `xrandr -r 100/120/144` I have no glitches at all with any resolution. Setting a modeline with `cvt -r` also works, of course the only other mode possible is 120 because it requries multiples of 60 but it has 0 glitches and it works even buy setting it in the .conf file -- You are receiving this mail because: You are the assignee for the bug.
