I used to have the trouble you are having, but with the recent quilt as I was sewing I kept my eyes peeled on the right side of the fabric, to see it stayed straight... the foot gives me the quarter inch seam and I know just where the quarter inch sewing has to be... and where the right side of the material should be... with all of the sewing my eyes don't stray from the right side of the fabric (where it has been cut)... hope this helps you.
