I am using NextJS with the SciChart trial license for development and suddenly got the error “SciChart: WebGL not supported! ” with Chrome. It worked fine before, and I didn’t change any codes for launching the chart. Also, it works fine with Firefox. The chrome version I am using is 107.0.5304.107.

BTW, the error is gone after I restarted my computer. Is it possible to be related to memory issue?

Below are my codes for initializing the chart:

  const initSciChart = () => {   
    // LICENSING //
           SciChartSurface.setRuntimeLicenseKey("xxx");

           SciChartDefaults.enableResampling = true;
    SciChartDefaults.asyncLabels = true;
    SciChartDefaults.useSharedCache = true;

    drawSpecChart();
};

async function drawSpecChart() {
    // Create the SciChartSurface in the div 'scichart-root'
    // The SciChartSurface, and webassembly context 'wasmContext' are paired. This wasmContext
    // instance must be passed to other types that exist on the same surface.

    let xAxesNumberRange = new NumberRange(0, 18);
    let yAxesNumberRange = new NumberRange(-140, -40);

    const chartDefinition = {
        xAxes: [{
            type: EAxisType.NumericAxis,
            options: {
                axisTitle: "Frequency (GHz)",
                axisTitleStyle: {
                    fontSize: 12,
                    fontFamily: "sans-serif",
                    fontWeight: "bold"
                },
                labelStyle: {
                    fontSize: 12,
                    fontFamily: "sans-serif"
                },
                visibleRange: xAxesNumberRange,
                zoomExtentsRange: xAxesNumberRange,
                labelFormat: ENumericFormat.Decimal,
                labelPrecision: 6,

                    fontFamily: "sans-serif",
                    fontWeight: "bold"
                },
                labelStyle: {
                    fontSize: 12,
                    fontFamily: "sans-serif"
                },

        series: [],
        modifiers: [
            { type: EChart2DModifierType.MouseWheelZoom },
            { 
                type: EChart2DModifierType.ZoomExtents,
                options: {
                    isAnimated: false
                }
            }
        ]
           };

       const { sciChartSurface, wasmContext } = await chartBuilder.build2DChart("scichart-root", chartDefinition);  

    xAxesNumberRange = null;
    yAxesNumberRange = null;
