Hi! Im not sure what can be happening, as i have the same gpu, and it works fine on my Linux pc (Ubuntu 22.04). I didnt try fedora but i can ask some coworkers to test.
About the negative normal maps, isnt enough to invert the x and y axis?
Oh. I didnt think about that. Thanks. And about black screen - my OpenGL is 4.6.0, but there may be some problems with Nvidia drivers, so I am working on it. If i would have some results - will write back.
