How can I find the default (font) resource a VT *instance* is using?

Setting up the virtual terminal appearance on a box with Arch and *urxvt*, I find myself unable to display which X resources are in use in a particular VT *instance*. Take that workflow: 1. Open an urxvt console, load a particular color/font/font-attribute (e.g. by editing ~/.Xresources then update this VT with xrdb merge) 2. Open another VT, load a different setting, and repeat so to compare between them. 3. Phone rings, time to eat or look upon some kid... 4. Come back to the computer: Oow, what was the X resources settings in VT 1, 2 or N already? I tried several tools that are able to show up X resources settings for a particular application but: As you might see, xrdb will show X resources loaded by the VT at *a moment*, but not per VT instance. Same for xorg-appres. Here's a wider screenshot with more instances and different settings loaded Is there a way to show up X resources loaded in a particular VT *instance* that you know of? PS: My question slightly differs from the otherwise very informative [How can I find the default (font) resource XTerm is using? ‒ 2013](https://unix.stackexchange.com/questions/96962/how-can-i-find-the-default-font-resource-xterm-is-using)
