Textures are loading several times, or overlapping multiple times

So the most blocks that are transparent or have 2d texture overlap.

On transparent blocks (glass block, glass pane, door, etc), the non-visible part is visible and gives a strange appearance. (seen on the pictures)

On 2d blocks (rails, iron bars, grass, etc), it flashes some black stripes (seen on the videos)

"How did it start happening?"
I don't know.

"When did it start happening?"
I think it started happening on the latest update, not sure.
