Bookshelves lag a lot while playing Minecraft with RTX. The lags are that textures, MER maps and heightmaps of several sides of some chiseled bookshelves are replaced with wrong ones or ones of another side of the blocks. I noticed the bug while playing Minecraft 1.20.30 on Windows 11 Home (I've got a Dell G15 5530 laptop and an NVIDIA GeForce RTX 3050 6GB Laptop GPU video card). I tried to change, delete texture sets and even reinstalled the game but nothing helped.
