Missing unmap by minimizing window #7636

Closed mse2 closed 6 years ago

mse2 commented 6 years ago

The window manager for Cinnamon does not unmap the client window if one clicks the '_' window frame button in order to minimize the window. ICCCM:

Reparenting window managers must unmap the client's window when it is in the Iconic state, even if an ancestor window being unmapped renders the client's window unviewable.

https://www.x.org/releases/X11R7.6/doc/xorg-docs/specs/ICCCM/icccm.html#changing_window_state

Steps to reproduce Run the attached program in a terminal, click the '_' window frame button of the showed black window. minimizewindow.c.zip

Neither muffin or mutter, that muffin is based on, do this. Other parts of the desktop environment rely on this behaviour so it's unlikely to change anytime soon.
