Can you tell us the value of:

  (frame-parameter nil 'fullscreen)

Immediately after startup?  Thanks.

I suspect Emacs is trying to resize the frame to accommodate the tab
bar, but the window manager isn't sending a ConfigureNotify event back
to Emacs.

IMO, tiling window managers should simply set
_NET_WM_STATE_MAXIMIZED_HORZ and _NET_WM_STATE_MAXIMIZED_VERT on all
windows, which avoids this problem completely, but they should at least
send a ConfigureNotify event to Emacs.

Which window manager are you using?

Thanks.
