Hi to all, I have a problem with Flat Tessellation(only in Linux). The problem is that when I enable Flat tessellation and after I try to rebuild light of level the engine crash(Output Log below), but if I use PN Tessellation(worse from my point of view) the engine doesn’t crash. I have already read all the post about Vulkan crash on Linux but no one talk about my problem. Someone can help me?
