What's Wrong?

There're already multiple posts about this and they're all automatically closed -- since 2.1.37, how is this not something drawing enough attention? Is everyone enjoying the huge dump of response at the very end?
Where did the streaming go(just like claude.ai and every other LLM interaction is like?)????
Where did it go and WHO decided it's a good idea to dump the huge blob of text at the very end?

I'm on Win11 WSL2, 2.1.37 is what keeps me going right now, all the newer versions just keep dumping all response once it's done.

Please bring it back!!

What Should Happen?

The response should present in a progressive way including the thinking process, just like claude.ai
