As far as the evf freezing during shots goes, one may have to get used to shooting with both eyes opened and track the subject with the eye that's not behind the view finder. It's awkward and takes some practice, but it can be done.
I can't, my left eye, I am left-eye dominate and always used my left eye in the VF, but it now has a bad cataract and horrible floaters so that I have trouble seeing out of it.
I switched to right eye in the VF and even if I keep the left eye open I really can't see anything with it
