Admittedly I've also noticed stretching/mismatching textures a bunch since the new update, notably if a wall is built, I remove part of it, say like 8 blocks, and place 8 new blocks of the same material, those blocks textures misalign with the rest of the wall. But if I rebuild the entire wall then it's fine.
I also noticed window textures are all stretched at times (the actual window frames ones), will take pics later if I remember to ^^'
