I have built a grating stimulus with the spatial frequency of 0.14, then I selected the option of “show info dialog”, it would generate the stimulus as expected as follows:

However if I cancel the seletion of “show info dialog”,it created a grating with an incorrect spatial frequency(it’s not obvious in the fowllowing figure), and the size of window became bigger than it under the correct settings(nearly full screen):

I was confused that parameters shown in the info dialog had nothing with my stimulus settings,so why it would cause this problem?
If anyone have the same problem, could you please help me to figure out the key to handle it ,thanks a lot!

I’m struggling to replicate this, could you upload the .psyexp file so I can try with the exact same stimulus you’re using?

I’m sorry to reply you too late!Here’s the .psyexp file about a single grating,with 0.14 spatial frequency and 180 of size,the unit I applied here was deg.When I canceled the checkbox ''show info dialog",it generated a grating obviously different from the normal one.Have you ever met the same problem?
