Similarly I get annoyed, if every pixel is some clickable action trigger.
This is the worst. It permeates all kind of GUIs. Windows has this mini preview windows that pop up when you're hovering over the apps in the taskbar. Also if you accidentally hover over them, all the windows are minimized except the one previewed.
Microsoft has systematically terminated every single way of disabling this idiocy.
Using one Windows inside another (vbox) at work is causing me PTSD. I'm no proud of it, but I think I'd use physical violence if I could confront the culprit.
