In a rear drive chair ideally you want 2/3rds to 3/4 of the mass on the drive wheels. The front casters should not be supporting much weight really at all.
All stock rear drive chairs sadly ship in a rediculously nose heavy configuration which overloads the casters which causes a mass of problems besides this one.
Such as making them very difficult to steer properly and it requiring a lot of torque to swing the front end with you on it from left to right. It also means low traction on drive wheels. Which means that they slip at every opportunity as you traverse what passes for our pavements and at the top of ramps etc and this means loss of control. It also means a longer chair with your feet too far forwards. As well as making them feel like an oil tanker indoors. On top of that it makes programming them very difficult as it sometimes takes huge power to initiate a turn or turn n place and other times very little. So unpledictable. And its a shame but all stock rear chairs are this way.
But they do not have to be this way. Move the seat back! Drill, hammer, whatever it takes.
This is I suspect the primary reason that people think they are so bad indoors. Its not because they are rear drive. Its because the way they ship. Why? They are trying to coply with a RULE that says that if you accelerate on a specific upwards slope it must not tip back. So instead they ruin the chair for every other use by sitting the occupant on the front casters!
Rant over! 
When my DIETS chair came I fixed it as part of its initial setup.
When my SALSA chair came, same shit.
When my Q700R cair came, I almost fixed it but its not perfect so I dont use it... Casters too close together.
When my original F55 chair came, fixed it.
When I modded/built the BM1,2 and 3, fixed it!!!
Should be like this:
