How to file a helpful issue
The problem you're addressing (if any)
Currently, popup windows are override redirect and not managed at all. This has lead to security vulnerabilities and other general badness.
The solution you'd like
Wayland has a much cleaner solution: the application provides the compositor with both the popup window itself, and with the constraints the compositor should use while placing it. Qubes OS should use this approach.
The value to a user, and who that user might be
Eliminating override-redirect windows will eradicate an entire class of bugs in the GUI daemon. It would prevent recurrences of QSB#072, and fix #4705, #6822, #5499, and #6518. It would also make fixing #6347 and #6256 much easier.
