How to hide wine app titlebar when window is maximized

Question

This is a quick post to show how to make wine app hides the titlebar and fully fill the vertical area of screen space when maximized.

In Unity DE, when Wine app is maximized, it doesn't hide the titlebar so the window can't be fully maximized. It looks something like this:

Answer 1

There is an easier way to do that. Open up your terminal and type winecfg. Then, choose Graphics and disable "Allow the window manager to decorate the windows" option, like so: Disabled "Allow the window manager to decorate the windows"

Finally, click "Apply" and that should be it.

Answer 2

The fix is simple. Launch CompizConfig Setting Manager (apt-get install compizconfig-settings-manager) and open Window Decoration setting and in the Decoration Windows field, delete the existing rule any, then enter (!state=maxhorz & !class=wine)

If you got that right, your wine app titlebar should no longer appear when the app is maximized and it will be shown back when you unmaximized it.
