This issue reproduced on Windows 10.

Describe the solution you'd like Some Electron application have option parameter "Disable to Hardware Acceleration". This option checked then can capture window (Ex: Slack, Discord)

I think add option to Disable to Hardware Acceleration.

Describe alternatives you've considered

It works when I tried either:

  • Windows Compatibility Mode sets to Windows 7.
  • Create a shortcut, add --disable-gpu to Target.

Additional context based on: electron/electron#16955

Reproduction Steps

OS and Theia version:

Research direction
The issue requests adding an option to disable hardware acceleration in the Electron based Theia IDE. First, locate the Electron main process initialization, likely in packages/electron main/src/electron main.ts. Look for how BrowserWindow is created and pass the ' disable gpu' flag conditionally based on a new preference. The preference should be added to the existing settings schema (e.g., in packages/core/src/browser/preferences). Review the referenced Electron issue for further context. There is no linked PR or assignee, so the implementation is open. Test the change by launching Theia with the new setting enabled and verifying that the GPU is disabled.
