We can see weird patterns in the samples.

Maybe it is related to the RNG ?

I had a similar issue that I fixed on my toy renderer using another RNG.

Could be, but I'm unable to see those repetitive patterns on my PC. What GPU are you on?

RTX 2080.

Can you point me to the place where the samples are generated?

The rand() function is in src/shaders/common/globals.glsl
and the seed is set in src/shaders/tiled.glsl
