Problem:
User attempts to add WMS basemap and receives the error message, “Draw Failed: Interface not supported (9934)”. Despite projection being set for the project and nothing blocking the basemap download (firewall, anti-virus, etc.), the user is unable to display a basemap.
Probable Resolution #1:
User is currently in an RDP session. Solution is to: “Configure H.264/AVC hardware encoding for Remote Desktop Connections. Double click on both the Prioritize and Configure and choose Enable and Apply.” This is quoted from the website: https://support.clo3d.com/hc/en-us/community/posts/360029315714-Graphics-Card-Issue-During-Remote-Desktop-Session
