Hi, When running Qt-5 on top of the directfb qpa plugin, some benchmarks are quite slow. (http://smashcat.org/av/canvas_test)
I've found that the 2D painting ops are going through the QBlitterPaintEngine class that is inheriting the QRasterPaintEngine class, which is doing all the painting via CPU. Qt provides another paintEgine class, QGL2PaintEngineEx, that is doing the same paintings via the GPU. So I want to know whether is possible to make the QBlitterPaintEngine inherit this QGL2PaintEngineEx instead of QRasterPaintEngine and got things working correctly or not? PS: the eglfs qpa plugin is going through the QRasterPaintEngine class too. regards Haithem.
