Ok, I think I know what's happening.
There is this new functionality that you're referring to, that
shows *modified* ignored files. The problem is that it does not
work right in 24.5. Instead it leaks *all* ignored files, when you
do g.
In 25 this seems to have been fixed.
With the behavior of x it's the same - this got changed in 25.
I don't mind showing *modified* ignored by default.
