Form Designer Loads Blank Screen or is Not Interactive

[system]

Why isn't my form created from UiPath.Form.Activities loading?

Issue Description:

Form loads as blank white form. Minimizing or maximizing the form window results in the form content displaying. The user is unable to interact with UI components like radio buttons.

On Iris Xe Graphics, UI elements don't refresh after they are initially rendered on applications that leverage Windows Presentation Foundation (WPF) when hardware acceleration is active.

Below are a couple of applications that have shown this issue:

• Amazon Chime
• Amazon WorkSpaces
• Amazon Backup
• Mitel MiCollab
• Luminar

This issue has been reported in the GitHub community and the Intel Graphics Community.

Resolution

Approach #1 - CefSharp blank screen when using Form Activity Designer:

To force hardware-accelerated GPU scheduling on Windows 10, use these steps:

1. Open Windows Search.
2. Search for ‘Registry’ and select the first option.
3. In Registry editor, navigate to ‘HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers’.
4. Locate DWORD tiled “HwSchMode”. Use value 2 to turn it On and 1 to turn it Off.
5. Restart the system.
6. Open Settings > Display > Graphics settings and toggle the option.
7. Restart the computer for the changes to take effect.

Approach #2 - Update Intel® Iris Xe graphics card driver to the most recent version.

1. Visit Support for Intel® Iris® Xe Graphics.
2. Download the latest driver.
3. Install driver.
4. Restart the system.

If the latest Intel® Iris Xe graphics card driver is not found for installation, follow the next steps:

1. Install the fix for this issue with Beta driver 30.0.100.9667 or a higher version of production drivers.
2. Restart the machine in the end.
3. Try to open the UiPath Forms designer.
