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,
                cursorLabelFormat: ENumericFormat.Decimal,
                cursorLabelPrecision: 6,
                drawMajorBands: false,
            }
        }],
        yAxes: [{
            type: EAxisType.NumericAxis,
            options: {
                axisTitle: "Power (dBm)",
                axisTitleStyle: {
                    fontSize: 12,
                    fontFamily: "sans-serif",
                    fontWeight: "bold"
                },
                labelStyle: {
                    fontSize: 12,
                    fontFamily: "sans-serif"
                },
                autoTicks: false,
                majorDelta: 10,
                minorDelta: 5,

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

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

    xAxesNumberRange = null;
    yAxesNumberRange = null;
};

Since Google have dropped their support for Silverlight in Chrome the online demo pages no longer work. Just wondering if you will be fixing this so that people can view the demos in Chrome again? Thank you.
