Web1 de dez. de 2024 · I solved it! The problem resulted from sharing a depth texture between two framebuffers. The reason for sharing the texture is that my question was actually simplified compared to reality: it's actually a depth-stencil buffer, since I need to share the stencil buffer between two framebuffers while the second reads depth values from the first.
