Issue Details

• Electron Version:
  6.0.0-beta3 & 5.0.1
• Operating System:
  Windows 10 (1803)
• Last Known Working Electron version::
  N/A

Expected Behavior

When I have a a HDR WCG enabled monitor attached and use desktopCapture, I try to capture a chrome browser with webRTC, or any application on the monitor and it should display a stream.

Actual Behavior

When doing this in electron it crashes immediatly with:
[20968:0515/234318.408:ERROR:dxgi_output_duplicator.cc(116)] IDXGIDuplicateOutput does not use RGBA (8 bit) format, which is required by downstream components, format is 10
[20968:0515/234318.449:ERROR:dxgi_output_duplicator.cc(116)] IDXGIDuplicateOutput does not use RGBA (8 bit) format, which is required by downstream components, format is 10

I assume this is due to the monitor being a YUV 4:4:4 10bit color ouput, disabling HDR & WCG fixes the issue however its not ideal as this feature works in a chrome browser.

To Reproduce

Try to run a webRTC video of a chrome browser with a HDR & WCG monitor attached.

  navigator.mediaDevices
    .getUserMedia({
      audio: false,
      video: {
        mandatory: {
          chromeMediaSource: "desktop",
          chromeMediaSourceId: selectedScreen
        }
      }
    })
    .then(stream => {
      handleStream(stream);
    })
    .catch(e => {
      console.log(e);
    });

Screenshots

Additional Information

Note it stream other non HDR monitors fine and some applications (file explorer) if they're NOT on the HDR screen(Chrome browser always crashes it when selected).

If I uncheck the HDR from the monitor everything works as intended.

Crash also happens if I don't try to do anything with the returned result.

I can use firefox and chrome webRTC without any crashing and it works fine with the HDR monitor enabled:

The web content itself will still be in 8-bit colors though, right? All web technologies seem to be standardized around sRGB.

Has there been any kind of fix for this with a new electron version or is it still broken? I'm able to reproduce this bug with Electron 25.
