This bug have existed for a long time now but I never could catch it.

The camera and layout selector panel will sometime just turn grey, no crash, no log event, I even tried to trigger this bug with flutter debug but I never could trigger it while debugging.

I can't quite reproduce it at will but it will happens at least once or twice a week. I have the feeling that it happens when I switch layout while a stream is still loading (but I'm not 100% sure) If I switch back to another view like setting and come back it will reappear.

Version: 3.0.0-beta20 and at least 5-6 previous versions, also on last bleeding edge
System: Windows (10) and Linux (Seen on Ubuntu 20.04, 22.04 and PopOS)

Thanks, the next time this occurs can you attach the logs in the settings.

This bug doesn't seem to produce log entries, I have these but the crash at this instance happens at 10:58

One thing I noticed is if I start the app, then switch layout few time the bug will likely occur, but once all the streams are loaded if I go to another tab and come back to live view to let this widget rebuild I can't trigger the bug anymore, hope this help.

This issue has been haunting us for a very, very long time. I have tried to fix it a few times (f98ed1b, e3f4ed5, 13105a3). Resizing the window usually fixes it. I believe the issue is that the Dart garbage collector collects our devices data when it shouldn't, causing to the Cannot assign Null to Iterable<Device> error.

It may be necessary to rewrite the sidebar logic.
