Hello,
we display raster data with our own layer based on your "MultiGeorasterLayer" sample.
Sometimes when I zoom in or change extent of the map by panning to another position the map seems not to be drawn correct.
As you can see on the picture there is a white line where the pictures come together. If I change extent e.g. I pan a little bit to the left the line dissapears. If I pan back the line comes back.
Any ideas?
