Hmmm, I don’t have any insight into why it isn’t capturing fullscreen.
The most elegant way of generating that particular kind of noise would be:
- render the stimulus with no noise
- change the blend mode to use multiplication (instead of the current options of adding or averaging)
- render some pixels that are either -1 or +1 at your chosen ratio (where -1 pixels fell they would essentially flip the color)
Actually, another solution might be to use the dedicated Noise stimulus, which I think does allow for more complex combinations of textures. I don’t have an immediate suggestion for how to do it but @schofiaj might be able to help since he wrote that stimulus class and thinks a lot about noise stimuli
