Visual Studio Code displays perfectly from a local display on a Ubuntu 20 installation, but just produces a blank white window when run from a remote Ubuntu machine through X-windows. Running code --disable-gpu doesn't help. Other applications such as Firefox, Nautilus, and Eclipse display remotely with no problem.
Any suggestions?
There is an issue for this upstream: https://github.com/microsoft/vscode/issues/110119
Running code --verbose --log debug --disable-gpu prints, among others:

I don't know much about X, but I would expect X shared memory (shm) to not work via X forwarding, and maybe it's something that vscode currently needs?
Just install an old version of VS Code.
I use version 1.59.1 and I don't have a white screen anymore when I use sudo.
It looks like it started in rev 1.66 on my Linux systems.
I uninstalled and installed 1.65 from here:
