My goal it is to accelerate my QWidget application in some way... I use the QWT library to render a curves..
When setting QT_XCB_NATIVE_PAINTING ( Qt >= 5.10 ) you are usually running into an hardware accelerated path, that is much faster, than what you get from the raster paint engine. That's how it is on all systems I'm running. If this is not the case on your system I would expect, that there is something wrong with your X11 setup. So the first thing I would try is to do some tests on a Linux/X11 desktop system to be sure, that it is indeed an issue of the BSP on your board.
Is any suggestions to minimize the CPU load on iMX6 target (using QWidget application)? Maybe is it possible to use an OpenGL at all with X11?
OpenGL has a lower quality without being any faster, than the hardware accelerated X11. And if your X11 setup on your board is not o.k. than the OpenGL path is probably not better.
