Comment (by mlennert):

 I'm pretty ignorant concernant the GUI display logic, but I see that in
 gui/wxpython/core/render.py, line 505, function Render(), is defined as


 {{{
 def Render(self, force = False, windres = False):
         """Render map composition

         :param bool force: force rendering all map layers in the
 composition
         :param windres: True for region resolution instead for map
 resolution
         """
 }}}



 then on line 520 within that function, there is a call to


 {{{
 self._renderLayers(env, force, windres)
 }}}

 However, _renderLayers as defined on lines 456ff:

 {{{
 _renderLayers(self, env, force = False, overlaysOnly = False)

         :param bool force: True to force rendering
         :param bool overlaysOnly: True to render only overlays
 }}}

 has force and overlaysOnly as parameters, but nothing concerning windres.
 The two mentioned parameters seem redundant and even contradictory as
 force = False should imply overlaysOnly = True, or ? In any case, AFAIU,
 _renderLayers seems to ignore the windres setting.
