Mullvad VPN graphical interface will no longer display after recent update & upgrade

[amd1890]

I have posted this issue with Mullvad and they mostly say they only support Ubuntu.

This seems like a Pop! OS issue then and if I can't get it resolved I'll have to stop using Pop! OS.

Issue:

Is it a bug?

I know this is an issue with the app, and contacting Mullvad support is not relevant.

I have checked if others have reported this already

I have checked the issue tracker to see if others have reported similar issues.

Current Behavior

The Mullvad VPN is not displaying any information at all. When I open it, there is a green lock displayed and it shows a notification of a connection. The lock then disappears. There is no window displaying any information for the App. I can check the connection using the command line and the tunnel is connecting. I can use socks in the Mullvad Browser.
Expected Behavior

App opens allowing features to be changed with graphical interface and lock does not go away.
Steps to Reproduce

Install Pop!_OS 22.04 LTS.
Install Mullvad 2024.8 and open App using icon.

Mullvad replied:

Thanks for reporting this! This looks like an incompatibility in Electron/Chromium. Unfortunately we don't officially support Pop OS. I can imagine this being connected to graphics card/driver as well.

We do intend to update Electron soon which might solve this issue.

A user suggested trying again but with a certain flag and it still didn't work:

You could try to run the app without GPU acceleration: /opt/Mullvad\ VPN/mullvad-vpn --disable-gpu

$ /opt/Mullvad\ VPN/mullvad-vpn --disable-gpu
