Hey kinetiksoft 
I’d be happy to help, can you provide a bit more info?
Indeed, I tried by myself from upgrading an “old” to the new Discourse version and this is broken, we’ll have a look at it.
Recent is subjective, and many things change over time.
Major changes usually have their own dedicated topic or tag, like sidebar, chat or Usercard Redesign Experiment
If you want to share opinion, feel free to participate in existing topics or open a new one in the proper category depending on what will be discussed
Which buttons, and how weird?
Can you provide screenshots and tell us if you use custom themes or components?
