I have the same problem on series x. I've also noticed that if there is no container open, but basic crafting inventory is open (with the 4 slots), cursor will jump to the top left slot of 4 slot crafting window. It seems to want to jump to the top left slot of whatever is available. It only started happening for me since the 1.19.80 update as well.
Thanks kelianor, I didn't know that. I just wanted to make sure this post stays active until they fix it so my wife and I can finally enjoy the shaders together. Seems not a lot of people still play split screen on console, sadly.
