I think there were a few planes with sliding canopies that still could not fly with them open because either -
1. the open cockpit created turbulence and disrupted airflow over the rear of the plane,
2. the low pressure zone created behind the windscreen drew exhaust gases into the cockpit.
Both of these effects would be more pronounced at high speed, but could be problematic even at takeoff/approach speeds.
Planes subject to these effects (such as the FW-190) would have to have separate modelling of "pit open" effects.
