Our Electorn app works in Hyper-V Windows, but fails to start on Ubuntu (20.04 and 22.04) in Hyper-V.
It seems to be a chromium issue: i.e. the electron binary starts, the window opens, but does not show any content (remains white) and we have these errors on the console:
2422:0708/095320.055217:ERROR:viz_main_impl.cc(188)] Exiting GPU process due to errors during initialization

I guess the relevant issue is Unable to access(W_OK|X_OK) /dev/shm: Operation not permitted
sudo chmod 1777 /dev/shmdid not fix the issue- I think the permission are okay:
$ ls -l /dev | grep shm drwxrwxrwt 2 root root 40 Jul 8 09:54 shm $sudo df -a | grep shm tmpfs 2009376 0 2009376 0% /dev/shm - we use electron
18.3.4 - the
App.Imageworks (tested on Ubuntu 20.04)
Any ideas? I am not sure, if this is related to Ubuntu, snap, Hyper-V or Electron...
Update 11.07.2022
When we start the app with --disable-gpu --disable-software-rasterizer (SO-ref), then the GPU related errors:
Exiting GPU process due to errors during initialization
InitializeSandbox() called with multiple threads in process gpu-process.
are gone - however, the app still does not start due to the shm issue.
