Check which deinterlacers are you actually using in the display
profiles (Edit the profile and look at the settings).  If it's Yadif
or GreedyH, that's your problem.  These deinterlacers are currently
"broken", in that they'll deinterlace everything even if it's
progressive material, hence the jaggy looking video.  That's if I'm
understanding the problem correctly from reading the dev and commits
list.  I know I encountered the same issue and it's especially
noticable with DVDs (most of mine are progressive).  They looked great
before and now, not so much.  There's a patch floating out there for
weeks but it hasn't been actually commited.
