Extension fails to load in GNOME 3.32

[ronjouch]

The usual! 😄, GNOME isn't exactly friendly with extensions backwards compat, eh 😕.

Here are the errors I see in journalctl:

gnome-shell[19665]: JS ERROR: TypeError: label is undefined

gnome-shell[19665]: Some code called array.toString() on a Uint8Array instance. Previously this would have interpreted the bytes of the array as a string, but that is nonstandard. In the future this will return the bytes as comma-separated digits. For the time being, the old behavior has been preserved, but please fix your code anyway to explicitly call ByteArray.toString(array).
                    (Note that array.toString() may have been called implicitly.)

I'm using the latest version available on extensions.gnome.org.

EDIT: new extension https://extensions.gnome.org/extension/1732/gtk-title-bar/ (github) seems to do the job.

From a no-title-bar (similar extension) request:

franglais125/no-title-bar#113

In GNOME 3.32 _GTK_HIDE_TITLEBAR_WHEN_MAXIMIZED is gone: https://gitlab.gnome.org/GNOME/mutter/merge_requests/221

They say that extensions should use _MOTIF_WM_HINTS instead.

I have fixed this issue in my extension (unite) and this is the final solution:
https://github.com/hardpixel/unite-shell/blob/master/unite%40hardpixel.eu/modules/windowDecoration.js#L86

More info on possible problems using _MOTIF_WM_HINTS:

For me it fails with the following error:

TypeError: global.screen is undefined

#178 (comment)
You have to change global.screen to global.workspace_manager I guess.
But the problem is in 3.32 the extension still doesn't work despite the change and I get errors similar to @ronjouch

In addition to already-mentioned extension "Unite" (which works but may be too invasive, as it tries to replicate Ubuntu's Unity feel), I just found extension GTK Title Bar - Remove Title Bar for non-GTK Software / https://extensions.gnome.org/extension/1732/gtk-title-bar/ , which is weirdly named but seems to do the job very well under 3.32 🙂.

Note that the global.screen error first appears in 3.30, is the subject of #195 but is not released yet (#177).

For me it fails with the following error:

TypeError: global.screen is undefined

Install the application not from extensions website (see #177) but from this repository.

GNOME 3.32 has been merged in #199.
