Rectangle at bottom right

There is a rectangle constantly displayed in the bottom right corner. It’s just 4 lines forming a white rectangle, the inside is transparent.

What does it mean? How can I make it go away?

My version is 17.6 for raspberry pi 3. Logs are at https://paste.osmc.tv/kazikiyije

I will be attaching a screenshot.

Here is the screenshot. I’ve put a circle around the rectangle.

If you try using a different skin, is it still there? Does it return when you change back?

Does it happen on local video playback?
I suspect you’re using a dodgy IPTV provider that are adding this…

It’s still there. I swigched from Estuary to OSMC and back again. The problem never went away.

Note that I can only see the rectangle when a file is playing. It’s not there when I use the interface.

It’s playback from a local NFS server. I’ll try copying the file locally and see what changes.

It is then an artefact in the video. No different to the Sky logo in the corner

Facepalm. I never checked other movies. Sorry for the fuss.
