Yep, I've seen it and experienced it myself. Had a Q500 with a .25 on the nose as a sport model. If I didn't take care to keep the model nose high so it was keeping the wing operating at a more draggy and higher lift coefficient the darn thing just would not come down on it's own. And rather than actually drive it into the ground I would just give up, power up and go around. I got to be pretty good at holding it comfortably near a stall. When flown that way it would settle in pretty nice.

But I don't consider that ground effect so much as it's poor glide path control where the pilot comes in with too much airspeed for such a relatively lightly loaded plane and with the low drag airframe it just takes the full length of the field to bleed off the extra speed. CP, I'll bet a lot of the overshoots look like they want to land by the end of the runway but by that time there's not enough left and it just goes into the weeds.
