How to fix common issues with Proton Authenticator on Linux

We’ve heard reports from Linux users with Nvidia GPUs that they’re unable to open the Proton Authenticator app and instead see a white screen.

This issue can be fixed by launching the app in the terminal via this command:

WEBKIT_DISABLE_DMABUF_RENDERER=1 proton-authenticator

This will disable GPU acceleration for Proton Authenticator and resolve the issue.

This is an issue on WebKit with Nvidia drivers. For more information, you can track the issue here(new window).
