Freeze shatter performance issue on Xbox

I play on Xbox series S and have a cold lightning warp build capable of clearing entire screens in seconds but the game becomes very sluggish when large numbers of enemies are frozen and shattered. The sluggishness persists even after everything is dead, suggesting that even ice shards on the ground degrade performance. I socketed elemental focus in my skills to stop myself from causing elemental ailments and performance improved drastically so looks like it's specifically about the freeze. GGG pls optimize your shatters.
