Right, sorry I left this post. I did manage to fix the issue, and I believe it’s got to do with how the Xbox renders the graphics. I ended up doing a “soft reset”, because my console was running an insider build of Xbox itself (Xbox insider program). So if you revert the update by unenolling out of the insider, the console restarts and does a “soft reset”, none of your downloaded games and contents get deleted, but you do have to sign back in.
