Sending longer messages in ongoing conversations with the keyboard up (especially in landscape) results in a good amount of stutter. Same with using control center or notification center over the keyboard. Lastly, turning with a keyboard open stutters a good amount as well. Why?? It even happens with third party keyboard which lack translucency completely. Apparently it's just a software issue rather than a weak GPU in my iPad mini 2, so hopefully it will get fixed?? Your thoughts and experiences..?
