QML on Toradex Apalis iMX6 quad

SeeLook

Hi all,

We are trying QML on Toradex Apalis iMX6 quad 2GB RAM with opensource Qt 5.14 and Torizon Linux.
But Qt demo example gives 11-12 FPS,
so even in a simple QML animation with scaling rectangle it is chopped:

Rectangle {
    x: 400; y: 100; width: 100; height: 100; radius: 10
    color: "red"
    Behavior on scale { NumberAnimation {} }
  }

But our main goal is to draw on QQuickPaintedItem with 50 ms rate.
Is QML on this device capable for that or Qt widgets would be the only option, what do think?

That hw is more than capable to run Qt Quick (QML) applications. Not sure how is your code in the QQuickPaintedItem done, but the mentioned 50ms rate translates to 15fps so it's in the ball park for the values you've mentioned.

@pasi thanks for the answer.

Yes, it is.
We just changed FHD resolution display to simple HD one and everything come back to normal, fps is above 30 now and QML works pretty good.
