Working with 6.4rc5 compiled as deb packages on Ubuntu Intrepid, many of
my students had trouble with the map display in the wxgui, today. I've not
been able to reproduce it systematically, yet, and so am hesitant to file
this as a bug, but would like to know if others have seen something
similar.
Sometimes, the map display does not seem to refresh properly. Symptoms can
be:
- zooming in the display shows you the new zoomed map, but also the same
map in the previous zoom state.
- adding a new layer does not make this layer appear in the map display
- changing colors or other display parameters does not change the
appearance of the map, even after a full redraw of all maps
Saving the workspace, closing the display and then reloading the workspace
normally solves the problem.
Any hints of what might cause this and/or where I should look for more info ?

I remember that the last time when I used GRASS/wxGUI for daily
teaching GIS at the university (in the of the winter semester) I was
facing to the similar problems. Currently I do not use GRASS for daily
work/teaching, so I forgot about this hardly definable bug. In the
worst case I will check it in the beginning of the winter semester.
Sorry I have not better solution right now, Martin

This problem seems to show up when the Map Display windows was covered by some other window. So, maybe some issue between the GUI and the general Window Manager (in this case Metacity in GNOME) ?

To continue on this: most of the time, I seem to be able to correct the problem by dezooming and rezooming again...
