I am also experiencing this problem with a normal awesome session
running GTK applications. I can reproduce it easily starting gedit.

Short version, try if

        $ xprop -root -remove _NET_WORKAREA

fixes this for you [1].

Looking for commits in `gdk/x11/gdkscreen-x11.c`

        $ git log -p origin/master -- gdk/x11/gdkscreen-x11.c

possibly fixing [2], I found the following commit [3]

        commit 2fcbe3a9b44491059170b71f75e07b3b24138c4a
        Author: Geoff Reedy <geoff at programmer-monk.net>

            x11: add missing checks that a hint is supported

            Before acting on any hint that is set by the window manager we must
            first check that the hint is supported by the current window manager.
            Checking that a property has a value is insufficient as it may have
            been set by a previous window manager which did support the hint.

            https://bugzilla.gnome.org/show_bug.cgi?id=691515

and looking at the bug report, this is supposed to fix our issue.
(Unfortunately the commit message, does not describe the problem and it
was not that clear. :()

I am therefore adding that upstream report 691515 [4] as the upstream
one.

Could you please try if building GTK with that patch solves this issue?


Thanks,
