Appears to be an issue specifically with OxyPlot.Avalonia. @VisualMelon suggests two changes:

  • Calling InvalidatePlot off-thread should set a dirty-flag immediately, and schedule an update on the UI thread (not just crash)
  • UpdateVisuals should check the dirty-flag and perform an update if necessary before rendering
