Tips to improve image tearing during animation with 2D renderer and LinuxFB?

  • I'm running a simple QML app using Qt5.8 on an embedded linux board (528MHz ARM cortex A7) with no graphics processor. I'm using QMLSCENE_DEVICE=softwarecontext for the 2D renderer. It's all working fine and the processor is coping but horizontal scrolling regions of the screen looks really bad with sections out of alignment during the animation.It looks like the problem is due to a lack of double buffering. Is that something that I can enable through Qt or in the linuxfb or both?
