Error related to TextStim?


#1

Hello

I’m trying to program an experiment where I provide real time feedback from an external source to the participant, expressed through a change in shape size and numerical score. However, I seem to encounter this error after a few hundred trials across many sessions (if nothing else goes wrong). I thought it was related to the textstim memory leak I read about previously so I tried using textbox. It seemed to work but because the shape and score are overlayed on top of each other, the score becomes masked by the shape. Therefore, I think I’m stuck using textstim. Does anyone have some insight as to why this occurs? Really appreciate the help!

I’m using PyschoPy 3.0.0b11 on Windows 10.
