Scichart freezing

Hi Kumar

Yes, there is a known issue Intel GPU drivers and WPF (not SciChart) on some PCs.

This issue has been around for a long time. See our forum post 9 years ago ‘Zoom not working on one single computer’!

• For a resolution. please see the bug reported on dotNet/Wpf Github: WPF – cannot redraw page on Intel 11th Core Iris Xe Integration graphic card

• Also see this bug on Intel website: Applications Using Windows Presentation Foundation (WPF) Don’t Refresh After They Are Initially Rendered

The Github thread above has the following resolution:

Just installed the 30.0.10.9667 drivers from 6/8/2021 and it appears to have been fixed. Running an 1165G7

Also another user suggests a workaround for computers with just Intel Iris GPUs

    // work around a bug in old intel drivers: https://www.intel.com/content/www/us/en/support/articles/000058136/graphics/graphics-for-11th-generation-intel-processors.html
    foreach (ManagementObject video in new ManagementObjectSearcher(new SelectQuery("Win32_VideoController")).Get())
if ((string)video["Name"] == "Intel(R) Iris(R) Xe Graphics" && string.CompareOrdinal((string)video["DriverVersion"], "30.0.100.9667") <= 0)
{
    System.Windows.Media.RenderOptions.ProcessRenderMode = System.Windows.Interop.RenderMode.SoftwareOnly;
    break;
}

Please try to check what video hardware is problematic and if it is Intel then try the suggestions above

Best regards,
Andrew
