Hello,
My customer would like to improve the performance of "Qpainter lines" and "Qpainter circles" measured by qtperf-qt5.
They used to run on i.MX 5 or 6 in a Qt4 QWS environment. However, when they moved to Qt 5.15 on the AM6548, performance dropped significantly on "Qpainter lines" and "Qpainter circles" despite higher hardware specs.
(Their application draws a lot of rectangles and circles)In Qt5 of AM6548, eglfs and linuxfb can be used as follows in addition to the weston environment, but their performance is also not good.
Do you have any advice to get better performance on "Qpainter lines" or "Qpainter circles" with Qt5?
Is there any possibility of improvement by using a version of Qt5 other than Qt v5.15?Regards,
