4115: Component start/stop in units of frames must be whole numbers


Component start and stop times/durations in frames must be given as whole numbers.


Since it isn’t possible to start or stop a stimulus part-way through a screen refresh it would be unwise to request that PsychoPy attempts that.

PsychoPy versions affected

All versions.


Check your stimulus start/stop time and set to an integer value instead of a decimal value.
