We're aware some players who are using an AMD graphics card are experiencing black screen issues when teleporting or loading the RuneScape client.
We believe this issue is caused by the latest AMD drivers.
As a temporary workaround, we recommend uninstalling and performing a clean install of your AMD drivers to Adrenalin 26.3.1 (WHQL Recommended) that was released on 19th March.
The issue is currently being investigated and we will provide an update as soon as possible.
