As you haven't answered this yet (most likely because listing all x86 scalability problems take time) I'll again ask another question that you didn't touch earlier:
If the decode problems are specific to x86 why are most studies in scalability limits done on RISC architectures? And why do they show that going wider than two wide gives rapidly dimishing returns?
