Suggestion / Bug Platform

The container title (Chest, Furnace, etc) and even creative Inventory-Tab names flicker in different colors.
No idea what triggers this and it also seems to be quite random.
I had all sorts of different colors show up which I sadly didn't manage to record but it ranged from white over gold, green, aqua to red and a few more.

This bug is not present since the latest update, it has been occurring for me since a long time I just thought it was already being reported as it's quite obvious and therefore would be patched with the next update. That has still not been the case which makes me wonder if this even occurs for other users. Now I'm reporting it!

Here's a recording of this weird behaviour:
