We’re running into an issue with Perspective in the browser and wanted to see if anyone else has seen this. Our operators often have a lot of Perspective HMIs open at once (16 or more in separate tabs). When they click back into a tab that’s already been open for a while, the entire screen is sometimes completely black for about 20-30 seconds before the HMI finally shows up again.
We’ve checked the browser settings to make sure tabs aren’t being put to sleep or discarded, and we’ve also recently turned off hardware acceleration turned off in both Chrome and Edge, still waiting to see if this makes any difference. We’ve seen it on Windows 10 and Windows Server 2022, using both Chrome and Edge.
We’re on Ignition 8.1.44. The Perspective gateway usually has around 60 active sessions and is dedicated to running Perspective only. Perspective projects are configured with a 720m idle timeout (set to Close Session) and a 5-minute session timeout. All of the HMIs are using real-time remote tag providers from remote Edge gateways, routed through a Ignition proxy gateway that manages connections from the edge and applies proxy rules.
Any help or thoughts are appreciated!
