Version information

0.3.0+build.5

Expected Behavior

I expected to have normal minecraft behaviour when breaking blocks and loading chunks.

Actual Behavior

When breaking blocks, it makes blocks of the same type nearby flicker. This only happens in situations when there are a lot of background apps open or a lot of ram being used.

Reproduction Steps

Open a bunch of java apps (for most memory consumption) and a few chrome tabs. Then allocate 2gb ram to minecraft. After that is done, you should be able to replicate this issue in a mountains biome with the stone block. Other blocks have some trouble with it.

Java version

Java 16

CPU

Intel Core i5-1035G1

Might be related to #819.

This also happens when:

1. Loading a new world
2. Rarely when loading new chunks

There was a driver update and it seems to have fixed it for me. I will test further.

ok so it happened once but it seems to be happening much less.

Does this still occur in Sodium 0.3.1?

Yes, it is still present.

Additional info: it also happens while placing blocks, although if you have already placed the block on that coordinate and broken it, it won't flicker. This also seems to be the case when breaking blocks that are part of a vertical structure, although I can't be sure about that.

Edit: nevermind, it also flickers while placing.

Now it doesn't happen to any block below y: level 61, although i will need to confirm this further.

Edit: just confirmed that nothing flickers below Y=64-61.

Edit 2: Oh. It seems to be fixed in 0.3.2 but i will need to check more.

Edit 3: nope, still there.

Edit 4: Now it's consistently NOT happening.

Update: the entire chunk flickers. Some coordinates will fix their flicker (mostly) after 2-3 breaks/places, while others seem to go on infinitely.

We have enough confirmations of this issue so far on Intel hardware, but it's still unknown what's causing the problem.

Merging this into #869 as it contains additional information and more user reports.
