My experience is that the syntax highlighter and the code completion can be 
running in different contexts, thus seeing different macros. See 
https://bugreports.qt.io/browse/QTCREATORBUG-25464
https://bugreports.qt.io/browse/QTCREATORBUG-25113
for two examples.

The time it takes to parse is dependent on how complex the file is. I have one 
very complex that is painful to use (probably due to use of Boost headers). 
The vast majority of files I work with are editable in reasonable time and I 
don't see any slow downs. This is on a 5-year-old laptop.

I cannot reproduce your problem of open/close/open.
