[Interest] Qt Creator is so buggy and so slow...

[Alexander Dyagilev]

Hello,

Often it just stops to suggest code, syntax highlighted stops working 
(at least for a part of the code) for no apparent reason.

It takes apporx. 10 seconds to parse c++ file for c++ tools to start 
working. If you open/close/open same c++ it can stop parsing it until 
app restart.

App restart often helps to fix these bugs, but they do return in a small 
amount of time...

Any suggestions?
