Hi guys. I have iMX6 board with Qt 5.11.2 and Qt-widgets based application. I have compiled my Qt with an 'xcb_native_painting' option.
I was hoping that this would speed up my UI and reduce the load on the CPU, but I was greatly mistaken: When the QT_XCB_NATIVE_PAINTING is not set, I got following top: * Xorg: 3.6 % * app: 12.8 % When the QT_XCB_NATIVE_PAINTING is *set*, I got following top: * Xorg: 23 % * app: 4.5 % What? QT_XCB_NATIVE_PAINTING makes it worse in 2x-times... WTF? BR, Denis
