First, what kind of grinder do you have?
Second, sometimes adding a layer of masking tape to the middle of the idler wheel to crown it a little will greatly improve tracking.

I was having this problem on one of my grinders the other day.I found out that my drive wheel had wore some and was a little out of line and making the belt run off funny.I also had this happen once when my platten had wore some.
If this is the problem it ois easy to fix by taking the wheel down to a machine shop and having them dress the face or drill the center hole out and put a shime in so it will fit the motor shaft.
Just some of my fixes for this problem,
Good luck.

Try some different brands of belts. I've found some crawl all over the wheel with even moderate pressure while others stayed right in place. Generally, I've found the cheaper the belt, the more it moves around. Your milage may vary.

You may have a good point I had a 3m 967 for hogging
and it did not seem to walk but when I drop to a 60
A/O it seemed to do it.
