Chunk is rendered strangely when using end_portal blockshape in RTX

I used the "end portal" blockshape (this bug does not occur when using the real end portal block.) and placed it one block away from the east side of the chunk.

Same rendering as turning off rtx and joining the world and turning it on.

You can easily check by apply the pack and placing red nether brick block at 64 4 64 or 64 4 65 and placing grass around it.
