<pre>Created custom modes and forced it into xrandr. 75hz flickers, but 73hz is
working fine it seems. This is on last amd-drm-next-staging

Will keep it like this for now and test it in games, but in kde plasma/chromium
73hz is smooth as silk it seems. Another thing I noticed is gtf generates
higher pixel clocks than the ones from my monitor (edid?). You can compare
above result with the attached xorg log.</pre>
