It is if the memory is held by the kernel for caching or buffering. Is it using an in memory swap file? If that’s even possible, I’m not sure.
I have no idea how that GUI thing measures memory usage, but if you run top in a terminal, it'll show free, used by programs, and buffer/cache separately.
zram is in-memory swap, but it's compressed/decompressed on the fly, so it shouldn't take up a ton of room, and certainly not at idle.
Sort the application in the bottom half of that window by memory and share the screenshot.
What else is open?
