Usually when moving around I notice sometimes white dots flash on blocks next to each other between connected blocks its mainly noticeable in caves and when daytime since they are transparent and not noticeable at any time of day and I have had this for quite a while now around 5-6months but quite possibly be longer, the images outlined with red circles are the artefacts in question, I believe it has something to do with Nvidia's antialiasing in the control panel I've turned off and on antialiasing but that does not seem to work and I still see the white dots on the edges and I have no idea how to fix it.

I have managed to reproduce it in a different world to the one shown I've done this by:

1.buildng stairs and connecting and rotating them in front of a wall in a arch like in the screenshots this works with full blocks stairs and slabs put next to each other or just normal blocks generated in the world mainly in caves randomly.
2.moving around while looking at the wall and stairs and the edges should have artifacts white dots and lines briefly appearing noticeably.
(side note) this most likely depend on the settings on the Nvidia graphics control panel so it may not happen but a understanding of this issue may be granted and will be appreciated.
