 This has always been a problem, but I haven't reported it because there
 were other issues to fix in the new wxnviz. But now that it is getting so
 much better otherwise, I guess it's time to get a track ticket on this.

 I open maps and switch to 3D mode and everything looks and works fine. I
 exit 3D mode successfully. No errors are reported during 3D mode or on
 exiting.

 I try to go back to 3D mode with the same maps and same display and the 3D
 interface does not respond or does not respond correctly, and 3D maps are
 not displayed or not displayed correctly (e.g., displayed without color
 and only while moving the puck; then the map disappears). I get error
 messages in the terminal and console. I'm pretty sure that this is linked
 to an error I reported earlier with a failure to load any maps 2nd time
 around (track #445). Here are the detailed error messages.

 Terminal message

 <Error>: CGContextRestoreGState: invalid context


 Layer manager console message
