Your stimulus size exceeds the X or Y window dimensions. Stimuli sized greater than the window size will not be completely visible.
This issue is often caused by an inconsistency between the units of your stimulus and the values being requested. For instance a size of 3, when the units are deg is sensible (3 degrees would be within the screen dimensions) but a size of 3 when the units are height would not be sensible (3 times bigger than the height of the screen).
All versions.
Check the size and the units of the stimulus carefully. You may also need to check the monitor calibration if you’re using units that depend on the monitor size and resolution (like cm and deg).
