A suggestion: try to use BetterDisplay’s HiDPI in reverse, rendering your 1440p monitor as 2880p (macOS Retina), then downsampling it to the native 1440p. There's an entry about it on their GitHub Wiki, look for "HiDPI, LoDPI"

For macOS, generically, you can run `screencapture -o -l $WINDOW_ID output.png` to screenshot any window. You can list window IDs belonging to a PID with a few lines of Swift (that any agent will generate). Hook this up together and give it as a tool to your agents.

And the compositor renders it unoccluded for the screenshot?

4K at 15" is 294 dpi. I'm very surprised to hear that you can see pixels at that density at a normal laptop screen viewing distance.

My laptop is 'only' at 226dpi (16") and I can't see pixels unless I bring my nose to the screen.

I think different people mean different things by "see the pixels." I can't imagine being able to see individual pixels on a 15" 4k display at laptop distances, but I can imagine being able to notice minor distortions in the outlines of text, or more discomfort than necessary when reading small text, as a result of lower pixel densities. That could be reasonably described as seeing the pixels.

My iPhone has ~320dpi and I can't see pixels at non-ridculous viewing distances. I don't know what GP's viewing distance habits or eyes are like but for me, considering laptop viewing distance is probably like twice that of smartphones, I can't imagine a 15" 4K laptop being anything but overkill.

Bitcoin is divisible to 0.00000001, so if a bitcoin was worth $10 million, the smallest possible transaction would still be worth just 10 cents (+ transaction fees).

Latest estimate is 'in 2 release cycles' (iirc), or 12 weeks.
