I am experience a rendering issue of a filled triangle. I have graphics card acceleration on. Why should this occur? Seems like a simple thing to render.
Sorry to hear about this experience and for the late reply. I hope the problem is resolved by now. If not, kindly try updating the drivers for your graphics card by following the steps shared in this article: https://helpx.adobe.com/x-productkb/multi/update-graphics-driver.html and share your observations.
