I've had to roll back to Update 1 Hotfix 1 as texture sizes were massive on some materials in my scene. Not sure if its to do with the triplanar node. No time to try and fix right noe so just rolled back and all is back to normal. I've opened a ticket with support too. Same on MacOS and Windows.
(I know my screenshot of the "wrong" one isn't fully resolved - but I was in a rush – but you can tell that its much larger tiling)
