Does not work in urxvt with X forwarding

[CyberShadow]

Hi,

I'm trying to use Überzug++ in yazi.

I noticed that image previews don't work over SSH with X forwarding. DISPLAY is declared, so yazi tries using ueberzugpp, but, nothing happens.

I can reproduce it manually, by running ueberzugpp layer, and then pasting e.g. {"action":"add","identifier":"yazi","x":1,"y":1,"max_width":48,"max_height":36,"path":"/home/vladimir/mpv-shot0001.jpg"}.

If I do this locally (not via SSH), it works. But, it does not work over SSH - nothing happens.

I'm not sure if it matters, but I use urxvt. It can't draw images by itself, so to show images, yazi needs to use something like Chafa or Überzug++.

For what it's worth, viewing images over X forwarding does work with ranger + w3m, which I believe uses the same general approach.

I am using ueberzugpp 2.9.6 and rxvt-unicode (urxvt) v9.31.

Thanks!

Sorry for not answering more quickly. Seems x11 forwarding doesn't work but could with additional code. I'll test some things out
