I am writing an application in PyQt6 and have a Grid (10×10) of QButton’s with icons made from a set of images that are merged (based on needed elements) using QPainter. This renders perfectly on my development system (Windows 11, NVIDIA graphics card, PyCharm) but the button icons show up as black or with some lines of graphics but nothing identifiable as the original graphics, on my Son’s gaming system (Windows 11, AMD Radeon graphics card).
