NOTE: 19w05a and earlier not confirmed, 1.13.2 has.
Either seeing chat with &k in it. Or using tellraw with it in 1.13.2, The font can glitch out and sometimes put all the letters in dark grayish. This has happened with me when I was playing Build Battle on Hypixel.
NOTE: No mods were used on 1.13.2, no resource or texture packs were used either.
What I expected was:
I'd have a normal game of Build Battle.
I got glitched fonts when I got a achievement for build battle.
HOW TO REPRODUCE:
Play any server that uses &k or use tellraw on singleplayer, multiplayer or realms,
Generate that &k tellraw or look at the &k.
You should see this is glitched out on 1.13.2.
Hypixel is a modded server. Can you please provide a /tellraw command so this can be reproduced in vanilla?
