The issue happened only once, and I couldn’t reproduce it, but to try reproducing the issue, here are the steps:
Open Minecraft
Open a world
I don’t know if you have to do anything in the world, but maybe just interact with some blocks and place some blocks
Quit to the title screen
Go to another app
Stay on that app for 2 minutes and type/click stuff

This is the F3 menu with the blocks with the bugged textures
