I set an shortcut to minimize every program,but it doesn't minimize firefox. Before you say that it's a firefox problem,the shortcut should minimize everything,so it's a kde problem.
Depends on how the PIP window is created I suppose.
(In reply to Nate Graham from comment #1) > Depends on how the PIP window is created I suppose. So if you mean what window class it is,it is not a sepatate window,so if I close firefox,the pip will closes. SO it's the same window class as firefox,but even if I minimize firefox,this doesn't get minimized.
