Display Errors

I really like modelling in Nvil and the tools but the display errors/inconsistencies are driving me crazy.

This is just one type of error I get. When I select the fuel filler cap it looks like it is above the fuselage mesh. When I select the fuselage mesh, the fuel filler cap looks like it is sunk inside. Which is it ?

I've fiddled with clipping planes but I found if I lower the near clipping plane too low then I end up with a transparent meshes.

My video card also has the latest drivers.

Looks like you have this option on: Edit > Options > Retopo Mode Enabled.

Whoops, that was it ! 
I'll have to remember that next time I start getting all sorts of display issues.
