Minecraft shader glitch?

I'm passionate about playing Minecraft. I recently tried a shader called BSL. I love this shader, but unfortunately I have a bug. When I mine blocks, the blocks that have been exposed are black. I then have to move away from the blocks a little and go back to them, then the blocks are completely normal again.

Thank you for your answers!

I think that's the shadow.

You are probably using an outdated version of the shader that is not 100% compatible with the latest Minecraft version. If you play 1.16, then specifically download the 1.16 version of the shader.

I will try thanks

If I move a few blocks away and go back then the blocks are colored normally again

Yes, that is also normal with a shader because you then no longer see the shadow there… But you can believe it with the shadow

This is an old version!
