This is kinda a rare bug but sometimes it happens but is brief, I haven't been able to figure out what causes it or how to reproduce it and it is occasional so it is hard to get a picture or video of it, but sometimes when you are breaking a block that is in the floor, the particles z-fight with the block you are breaking

Edit: I'm not sure if it's z-fighting with the block itself or if it is with the breaking animation, I just see really brief z-fighting on the breaking particles

The actual effect looks a lot like MC-117932 but it isn't caused by landing, it's caused by breaking blocks and I don't think it is just when you are looking straight down, but i may be wrong on this.
