i got the same problem after upgradeThis is what stopped working yesterday after my update. I just get the red border now. Am I to understand that this fixed your problem?
Just tested its possible to uncheck local file box on Linux and use the file:/// before and it works again.On my Linux with OBS 27.2.1 and Windows I need to put my animeted lower3rds on a http/http webserver both files for the docker ui and scene
to make it work - I was told it was because of newer chromium parts used in OBS.
This solution worked for both my Linux and my windows OBS - both new verison of OBS did have the same problem with animated lower3rds.
file:/// <--- Adding this also fixed mine as well. Its running fine now like normal.Unchecking Local file check-box and updating the path post sorted it for me. Basically it was just a case of adding file:/// on the front of the URL and changing all the back slashes to forward slashes and that worked for me.
This fixed it for me:
Free - Animated Lower Thirds with Dockable Control Panel
I found this thread trying to figure out why my own BrowserSource overlays weren't working - and thought I would take a look at the code in this plugin. It has the same issue I was having - this plugin uses BroadcastChannels to communicate between an OBS Dock and a BrowserSource on a scene...obsproject.com
