Description

Expected Behavior

Scratch desktop should open and run

Actual Behavior

Scratch desktop opens, and displays "WebGL Not Supported"

Steps to Reproduce

Remote Desktop into the raspberry pi (I used Raspberry-Pi-Remote-Desktop-macOS)

Open Scratch Desktop (Error: WebGL Not Supported)

Q: Could this be an issue with the Remote Desktop application?
A: No. WebGL worked just fine in Chromium when launched from Remote Desktop

Q: Could your GPU be blacklisted?
A: No. Scratch Desktop works just fine when launched straight from the Pi, not through Remote Desktop.

Suspicions: Possibly an issue caused by the edits that Electron makes to Chromium.

Operating System and Browser

Raspbian-GNU (Linux 10 Buster), Raspberry Pi 3B

Research direction

Reproduce the issue on a Raspberry Pi 3B running Raspbian Buster by launching Scratch Desktop through the reported remote desktop connection, then compare it with Chromium and a direct launch on the Pi. Investigate the Electron/Chromium WebGL behavior in these environments; done means Scratch Desktop opens with WebGL functioning over the remote connection.
