Summary:
A white light is flashing on the white glasses in Minecraft Bedrock edition.

Steps to reproduce:

1- Build any structure that has a lot of white glasses together.

2- If you are in survival mode, walk a lot towards the structure you built or if you are in creative, fly towards the structure with white glass.

3- Or you can run making some jumps that also works.

Observed results:

Every now and then, you will see a white light flashing rapidly on the white glasses.

I just want to remember the white light only flashes sometimes.
