nividia card problem???

whenever i load in to my mcpe w10 (astral client) (also tried without astral) i always see that the boxes arent together (split) and when i join a world my mcpe w10 gives me a black box as a cursor (cursor is there but black box is bigger (more annoying)) this all happened when i got the new nividia card upd and now it looks like this and so sloppy fix this please :/
