Lava Can randomly disappear/Go Invisible with Ray Tracing

I was caving & I randomly fall into a pit & started burning, I got into creative mode, then started breaking stone blocks and they started getting replaced with Lava blocks, all of these were with ray tracing turned on, I turned RT off & Lava magically re-appeared in put, it was a weird experience & a weird bug, I currently can't provide a way to re-produce it but I've been seeing people complaining about this bug lately, so I'm reporting it for now until I find a way that can Guarantee this bug happens.

Those few Lava blocks you see in the middle are where I destroyed the stone after I got in creative mode.

Now with ray tracing turned off:

Lava magically appeared in It's place.

I faced this in latest beta & I've seen other people reporting this issue to me.
resourcepack was (https://mcpedl.com/truly-vanilla-rtx) but I Highly doubt a PBR resource pack can cause this (there's even someone in comment section there pointing out this bug!)

My Current way of Re-producing it.
1. Create a world with a PBR pack & ray tracing + Caves & Cliffs toggle enabled
2. Start going around in caves & find some lava pools with ray tracing, you should be constantly switching in caves because there's a high chance you will miss Invisible Lava polls with ray tracing turned on.

I'm still not sure about the exact cause of this, It randomly happens in some situations.

Hi

Do this issue still occur? If it does could you please upload world where it occurs?

 

This ticket will automatically reopens when you reply. 

I was no longer able to re-produce issue in newer betas & after this report.

even in the same world, it no longer happened, might be a very rare one under very specific conditions which I don't know, I will attach more evidences/world if it happened ever again in future.

Could not reproduce, and I have no idea what this issue can be about. 
Resolving for now. 

I believe it was something to do with a bug that was in beta 1.17.0.52, which caused all liquids under y=0 to be rendered improperly. It was fixed in the following beta.
