textures overlap each other

Hello dear Minecraft developers this morning I played minecraft previewHello dear Minecraft developers this morning I played minecraft preview 1.9.40.21 And I found a rather interesting bug while pressing the button to exit Minecraft, the texture of the market climbs onto the exit button of the game. I think this can be fixed simply by recoding the textures Unfortunately, the support site itself is not allowed to select this version, but in the description I indicated that this is this version and the screenshots also show it!
and i also checked on my android device and There was a problem...
