Description

@Milkitic

Issue: Checked #2848 and #2419, but it seems that the issue is not actually fixed in the latest branch. It causes critical performance issues in Linux systems.

ScottPlot Version: 5.0.21

System Version: KUbuntu 24.10

Avalonia Version: 11.0.7

Screenshots:

Reproducing:

   double[] dataX = { 1, 2, 3, 4, 5 };
   double[] dataY = { 1, 4, 9, 16, 25 };

   AvaPlot avaPlot1 = this.Find<AvaPlot>("AvaPlot1");
   avaPlot1.Plot.Add.Scatter(dataX, dataY);
   avaPlot1.Refresh();
