Hi, i have been busy coding a fairly involved setup using psychopy 3.0.0b2 with python 2.7 in pycharm. So far it worked out fairly well overall. I encoutered a bug with text stimuli and decided to upgrade to psychopy 3.0.7 with python 3.7. the transition was mostly smooth but now i encounter some s…

Issued a patch here which seems to fix all the problems around having mixed window configurations. WIP - BF/EN: Fixed drawing on multi-window displays with heterogeneous configurations. psychopy:master ← mdcutone:master o…

I realized my problem description was not very clear. I updated the code to better illustrate the problem. based on the code, you yould expect a simple square to be drawn on both windows. This happens only for the first frame, on subsequent frames the scaling is thrown off, causing the square to be…

Are you on a Mac? This sounds similar to an issue I encountered. I developed a fairly kludgy work-around. [image] Mac multi-display bug (on non-retina Macs) with Pyglet on PsychoPy3 (but not 2) Coding Aside from my previous struggles with retina displays , I’ve discovered …

That seems to be the same issue from what i can tell, the behavior is very similar. I am on two windows machines, win7 and 10. I think the Issue is independent of platform. In the .flip() method of the .window class the line: self.resetEyeTransform(False) # reset transformations seems to reset …

Hello, These changes were introduced to allow the window class to handle different projections. It should be able to handle windows with different resolutions, however there seems to be something I missed. I’ll look into it and see if I can issue a patch.

Thank you for looking into it and fixing it so quickly!

Usually, I use matched displays all sharing the same attributes (i.e. size, color depth, etc.) to present multiple windows, so other cases slipped through when testing it out. :confused: In the process of fixing this issue, I found and fixed some other problem behaviours when using multiple windows…
