I’m designing a fairly simple study - basically a version of the Stroop task. Have subjects press a button in response to an image and a text prompt (which are randomly paired with each other).
With larger images (600kb), things seem to run OK for 15-20 trials, but then I get a WebGL:Loss of Context error. I’ve tried it in Firefox and Chrome and get the same error, around the same time point.
Note, it doesn’t seem to make a difference whether I upload just the stimuli I need, or include some for a second condition.
Also, everytime the a new stimulus is presented (whether a real trial or an instruction image, or just text rendered on the screen), I get a warning from WebGL: Error: WebGL: texImage2D: Conversion requires pixel reformatting.
To replicate errors from the web side, see here (and enter any # under participant): awssmweis.bitnamiapp.com/friz/
Please let me know if more info would be useful, or if there is some simple setting I’m missing in the Psychopy Builder before I export.
