Here's a photo from the artefacts i'm seeing:

 I think we found a fix. A glsl pow value was not properly clamped. Fernet is reinvestigating some details but said to PR the fix today. Thanks for the report.    

Hi guys, any news on the black artifacts issue?
tried 0218, still there.
thanks   

I can confirm that the artifacts are still there in 0218 despite the "OpenGL: fix NaN in shaders" fix.
