Let's play a little game...
What is working in this picture that shouldn't? Can you tell?
@falktx something very bizarre - the spectrogram shows up properly in context, but clicking on it makes it black. i wonder if this is a bug in the client I'm using?
as for what shouldn't be working... no clue. the position of the meter suggests itself but i don't think it would be that obvious. some plugin format wizardry perhaps?

@snailerotica oh wow you found something I was not expecting. the image renders incorrectly for you very odd 🤔
as to what shouldn't be working, let's say at some point Ardour removed support for gtk-based plugin UIs 😉
@snailerotica and I think I know why the 2nd image is rendered wrong, my theory is because of bad image down-scaling.
I can see the artifacts from a fast but bad resizing, where the algorithm just skips pixels to match the target size.
Seems to me the image has exactly the black lines on the spots where this algorithm would show a pixel/line. A proper one would do an average filter so each downscaled pixel takes into account surrounding pixels too.
