What hardware are you running on? Not seen any issues with sha-256, but we had and issue with a client ssl profile change(removing insecure protocols)under 11.4 Exactly the same issue i.e web page wouldn't always render correctly when backed out everything worked . It only seemed to affect our 2000s and 4000s hardware, In the end we fixed by upgrading to 11.6 HF1. The only thing we could put it down to was a possible issue flagged under SOL15232. Just a thought.

    Same as us. Traces weren't obvious for us, only that certain pages didn't render almost like the CSS content had corrupted. If your running HA pair I'd suggest at least upgrading one and failing over to test if you can.
