**Description**

The "lots of circles" error page is very rough via Remote Desktop connections. In the current global pandemic many people are working remotely via already constrained connections. Needless redraws caused by the highly animated circles can cause frustrating slowdowns and sometimes lost connections.

**Use case / motivation**

It should be trivially simple to disable the animated portion of the error page and instead use a standard error page. Ideally this would be something easily achievable via configuration options and exposed in the Helm chart.
