Black background on image overlay

Hi there! No, I was never asked to re-locate the file and the file location never changed. I have all files related to the project in one folder and all other files are working, so hopefully there shouldn’t be an issue with the file location?

Just ran a new installation of shotcut, removed the tracks with the overlay. Removed all the old images. Loaded a new image into playlist. Created a new track. Inserted image. Same problem … doh

I just found this thread in the forum:

Here they solved it by activating an option called ‘composite’ on the track - I don’t see this option. Does it still exist?

Is there any kind of setting for ‘track background’ or adding an alpha channel to a track or anything along those lines where I could be looking?
