Regarding the serious issue of resource pack loading

Whenever I start the game, there is a chance that some button textures will be incorrect.This kind of problem sometimes occurs when I enter the world or withdraw from it.In the previous version, there were never any of these problems. I suspect that the change in file format has led to the alteration in the way materials are loaded.This kind of problem is only likely to occur when in full-screen mode.It's truly ironic that BE has all these convoluted mistakes.
