Trackpad of magic keyboard on ios 14.2

After updating my ipad(ipad pro 12.9 3rd generation) to ipados 14.2 there are some bugs with trackpad especially when i open “setting”. The work of trackpad seems to be not effective as before. Also the size of pointer control increase which is not good. I wnt apple support to fix this issue. By the way if there is any solution for the less effective work of trackpad, please tell me. Thank you very much
