What I did here is start off with live tv (which should have been @50
because we have PAL broadcast) then moved to a 24p video , then back ,
then another 24p video ,then back . But none of that actually happened
properly , and I could definitely see judder .
This is my xorg.conf , I had to remove some modelines because the new
behaviour at random chose rates that looks like the TV did not support
such as 29.97 . This happened after switching between live tv which
shoud be 50 and getting back to the desktop which used to go back to 60
frames . My tv is an old Sony KDL-46X3100 .
