Filtering "yellow"turns off red errors/warnings.

If I turn off warnings of compiler in qtcreator, it turns off ERRORS as well, except for current file. I.e. if no file opened = "no errors"

If i double press "show warnings" button, then it restores itself ok as i got used to be.

Also switching active editors hides "red" errors IF button unpressed ("show warnings", i.e. i want to see ONLY reds for whole project).

Oh, and this project is "cmake", possibly on qt project its ok with errors. Didn't check.
