Rendering problem with QML

Balaji Sivakumar

I have created the canvas graph on qml, and it's not rendering, only when I minimize it and maximize the application it renders correctly. So does anyone know about this kind of problem?

System Spec:
Windows 10, 64bit
Qt version: 15.12.9

**1. A graph was not rendered before minimizing **

**1. A graph was not rendered after minimizing **

Hello,

did you try changing the default renderStrategy value to use a private rendering thread or rangerTarget to Canvas.FramebufferObject? Maybe making some adjustments on those properties can help you.

thanks for replying @GabrielRR .

I will check with your suggestions. And can you give me some more explanation on that, I'm not that good in Qt qml.

Post your Canvas object and code used for rendering. I cannot tell what you are doing.

@Balaji-Sivakumar Sure, I think those are options you get to make a better rendering on what you are doing currently, if you need further explanation maybe you can check the following documentation:

RenderTarget: https://doc.qt.io/qt-5/qml-qtquick-canvas.html#renderTarget-prop
RenderStrategy: https://doc.qt.io/qt-5/qml-qtquick-canvas.html#renderStrategy-prop
