I have no third party terrain or afcads.
The problem persists.
Un-install & re-install & double check you selected the 3d bridges. The flat bridges are a performance feature for those that want it. If its still flat, try loading at a different time of day & not from a saved flight.
All that could prevent it working correctly are third party afcads, which can come from anywhere. Or maybe global terrain/mesh packages.
