Problem with 1st time display
I've got a problem that is not that important (I implemented workarounds) but still.
In my experiment (OpenSesame 3.2.7, psycho backend), for the instructions phase, I want to show participants screenshots of the task. The problem is, when I coded the experiment on my computer (Windows 10 17763.369, Graphic card: GTX 660M, latest driver, 1920x1080@60Hz) everything was fine.
But when installed on the test computers (Windows 7 SP1, Graphic card: Radeon HD 7450, don't know driver version, 1920x1080@60Hz), the first screenshot I want to show just doesn't display (I implemented a dummy 0ms canvas with an image and this way, I can display any image I want afterwards). The very first fixation dot of the experiment is also randomly distorted (same workaround, dummy 0ms fixdot and everything's fine). Finally, my color wheel looks also a bit worse on the test computers.
Do you have any idea why this is happening? Should I maybe upgrade the graphics driver of the test computers?
Thanks for your insights,
