It's acting like memory iis being hogged somewhere, but I can't figure out where. Load-App didn't reveal the culprit, just added to the slowness of the 770 by using even more memory.
Sounds like a hardware problem. Just to be sure, try re-flashing to the old firmware (scirocco) and see if you experience the same slowness.

When I get a GPS fix, while sitting here in my office, the little blue dot "drifts" and the speedometer shows from 0 to 5 MPH with occasional leaps to 60,75,90 MPH! So, I start getting a red track laid down. Sometimes, it's just a small (several block) track, other times it's a long straight red line going for miles. Remember, I'm just sitting here! I should add that I'm only getting 3/11 satellites now.
Maemo Mapper gets all that data (location, speed) from your GPS receiver, so if Maemo Mapper says your speed is 90 MPH, then that's what your GPS receiver is telling Maemo Mapper that your speed is.

Maemo Mapper uses black to represent areas of the screen that do not have maps downloaded, so the only times you should see white are if they are in the map data itself, or if there is a bug in maemo that keeps Maemo Mapper from drawining in the areas.

Try running from the command line (xterm) and see if you get any errors.

All in all, if you just re-flashed and haven't installed much on your system, then it sounds like you have a hardware problem and need to see Nokia about getting it repaired or replaced.
