It can be both. The materials can warp with heat causing mechanical interferance and the aging electronics can also malfunction when the cockpit temp spikes. Typically once you are traveling down the road and air is moving through the cockpit the needle will unfreeze.
To determine which it is you can carefully remove the glass.
