Yes, in a fullscreen video, the cursor changes to a 'Nothing to do here' cursor when over the area that would trigger the blue effect. The cursor is a 'You can click here' cursor everywhere else.

So should I register this as a bug...?

Looked into it, it's a bug in plasma/shell/panelview.cpp which just exits early when there's _any_ fullscreen window, leaving the huge input trigger in place, occluding 30px of the fullscreen window.

I'll test a patch and link the review request here.

This is actually this bug: https://bugs.kde.org/show_bug.cgi?id=217560

Ah, I didn't find that bug when I searched around for an answer! Thanks for pointing it out for me. I'll keep an eye on it to see if a fix gets done

My name is Oxen Underscore and I do not approve of this bug.

I still have this problem in Linux Mint 17.1 64 bit KDE.
