display bug with icon-data

Created by: Try2Code

hi!

I tested psy-view with icon data generated by

cdo -f nc topo,icoR02B05 ti.nc

initial plot with psy-view works fine, but when I zoom in the whole canvas is painted with contour colors:

when I click on the canvas once the map gets re-drawn and everything looks fine again

This does not happen with regular gridded input file

cheers ralf

I use psy-view 0.1.0

Output of psyplot -aV
