So, I write PHP with UEStudio, and every time I write a string or comment, example print "foo bar"; or //this is comment, it's so slow that I need to wait one letter per second as it's trying to get some hint messages for PHP functions.

How the hell do I get rid of it in strings and comments?

Both options are checked and have been for a long time, but it doesn't have any affect on it.

Unchecking Show symbol list automatically removes it, but then it removes whole hinting from editor.

Hmm, I unchecked them (disable this feature from strings and comments) and editor became faster again with hints.
Then checking them again on, editor slows down and it shows hints :(
