Artifacts in Blender 2.80 with EEVEE and Firestorm 6.0.2

Hi, I’m not sure if this is the right place to mention the artifacts that seem to arise lately.

The problem occurred to me in Firtestorm64 6.0.2 for Linux. A Second Life viewer (see 1st picture) then when consulting the Firestorm support group, a guy told me he experienced the same artifacts and could reproduce it in Blender 2.80 (both AMD & NVidia) (see picture 2).

So we guessed both rely on the OpenGL shaders…

Anybody who can help solving this artifacts?$zVXK6Vf3$CTiQ9cL.png
