Thank you for your feedback. Both of the behaviors you experience are known issues.
The first one, as you have noticed is because sometimes the analysis does not complete fast enough. Since performance is very important for us, we are going to do our best to fix this issue as soon as possible.
The second issue is caused because of the formatting feature of the typing assistance. When you hit semicolon we format the current line. We move the semicolon to the place where it should be, however after the format - this position is no longer the correct one.
A temporary workaround could be to disable the automatic format after semicolon hit.
I am sorry for the caused inconvenience.
Thank you for your feedback!
