I might not understand the functionality correctly, but I believe, that it should filter out methods that contain somewhere in the name things that I type into the field. 

CPU Profile any project, take a snapshot during the run and under the data put something in the field, where it's written Method Name Filter. 

While I was writing this bug I tested some stuff and realized, that it always filters out everything, even methods, that should pass the filter, IF they are inside a method, which does not pass the filter. Is this supposed to happen? This way one can only filter out the top level methods and everything inside these methods, that does not pass the filter. I would expect to be able to go the other way around, from the bottom of the stack trace up. If the methods inside a method are filtered out, okay, but if one of the methods passes the filter, it stays highlighted, within its stack trace (even though the stack would constitue methods, which would not pass the filter - they would not be highlighted or so...)
