I also wonder if your knees are tracking properly. It might just be a matter of being more conscious of knee tracking while you squat. Knees track the pinky toe. This can be much more difficult in a wide squat for many people.
Cues for this:
-knees out
-spread the floor
-screw the feet into the floor
Is wide squatting your strongest squat? If not, it wouldn’t kill you to stop a little above parallel.
