THE BUG :
While changing the day-time, the Ray-Traced renderer does not work as intended.
We can compare that with the COVID-19 speading all arround the world (the world is going black).

HOW TO REPRODUCE :
Resource pack used : https://mazewave.github.io/vanilla-raytraced
Try to change the time of the world using /time set day/midnight while moving arround.
It will not work everytime, good luck with this.

Let us know if issue still occurs. If so, can you please add it to the affected versions (or mention it if you are not the reporter).
I found that this bug is possible to reproduce in the last stable version 1.16.221:
How to reproduce :
1 : Create a perfetc mirror texture, if you don't wanna create a PBR resource pack, here is one :
2 : Make a flat word
3 : Create a giant cube : 115x20x155 (x/y/z), the cube need to have the mirror texture when Ray-Tracing is switched ON.
4 : Go in the cube you have just created and seal it. (Do not get any light in)
5 : Turn ON Ray-Tracing.
If it works as intended, you will see a dark world (because the cube is seal)
6 To make the bug occur, you'll need to toggle ON/OFF Ray-Tracing fast enough to make the DXR engine to create theses artfects shown before. You can use the "$" key to toggle ON/OFF Ray-Tracing while playing (AZERTY keybord layout because I'm French)
After few tries, it should work.
Bonus step : If it doesn't work in 1.16.221, place some emmissive blocks such as sea lantern or shroomlight; You can download the Main resource pack used here.
