I've removed workaround introduced in r54958 with pure gdk/gtk 
implementation in r54975.
Please guys test, since I cannot reproduce problem here (even without 
any patch): Fedora 24 64bit, KDE Plasma (kwin is window manager).
I need info from users from Mint 16..18 and Cinnamon DE which uses 
mutter or metacity if this finally fixes problem.
Positive feedback = merge to 1.8RC2

Important note: Gtk2 changes window state in async mode under x11, so 
statement like this won't work (it works ok under qt or win32) and you 
can expect problems with such code :)

with TForm2.Create(Self) do
begin
   Show;
   LCLIntf.ShowWindow(Handle, SW_SHOWMAXIMIZED);
   LCLIntf.ShowWindow(Handle, SW_RESTORE);
end;
