[MCPE-194362] Chunks Flickering With Ray Tracing

As of 1.21.70, placing and breaking blocks causes chunk meshes to momentarily flicker when Ray Tracing is turned on. See attached video, sourced from https://www.reddit.com/r/minecraftRTX/comments/1jk31h5/screen_flickering_when_placing_or_breaking_blocks/

Happening in my BDS world as well. Also occurs when pistons move blocks.

Breaking the stone block causes some nearby blocks to appear to change to sand for a split second.

This only appears for a split second as a “flash”, had to check frame by frame in order to see what it was doing.
