Note 1: This bug happened in version 1.16.1, not 1.16.5, but there was no option.

So, I was filming footage for an upcoming video of mine, and unexpectedly, my Minecraft started to glitch out very badly. The attached files below are clips of the Bedwars game I was playing when this started. After the game I went onto a different server I play on, same problem. I restarted my router, didn't work. I restarted my computer, didn't work. All of this took place yesterday, and when I got on today it was fine, but after that game yesterday it was going on for hours with no sign of stopping. Although the bug is gone, it was still a major problem.

If you do want to see the entire full game to see everything that happened, you can watch it here Monday at 11:00AM EST.
