<p>Recently I am having trouble with all the zoom and pan functions
in the map display. After first showing a map, the display is
zoomed to the full extent of the map (as in Settings). But none of
the zoom or pan (or mouse wheel) functions work. That is the map
display does not refresh. If I then slightly resize the map
display window the display refreshes and zooms or pans to the new
region. If I add another map, it does not show, and "Zoom to
selected map" does nothing. But again a slight change in size of
the display window - just nudging the corner a bit - apparently
triggers a refresh and the display zooms to the new map extent.</p>

<p>Here's what I get in the console:</p>
<p><br>
</p>
<p><tt>(wxgui.py:10767): Gtk-CRITICAL **: 11:12:15.192:

<p>I am seeing this on Linux Mint 19. I tried to delete the
./grass7/wx file, and start with fresh GUI settings, but the
problem appeared immediately. I also switched to the png driver,
but no change.</p>
<p><br>
</p>
<p>Any suggestions?</p>
