Hi, not really sure how to describe the bug but in QtCreator 4.12.1 (Windows) autocomplete is kind of broken. In previous QtCreator when I wrote in code

"this." it was automaticaly replaced by "this->" in 4.12.1 its not replaced automatically.
Suggestions for function is also super slow around 6 seconds in the previous version it was almost instant.

Is there any setting I could try to fix this? or its already reported bug?
