This is occurring for me too, here are screenshots comparing the output window to the terminal window, note the terminal version is blurry. the images are not inline as github does some scaling on image:

Additional terminal settings:
"terminal.integrated.scrollback": 10000,
"terminal.integrated.fontFamily": "Courier New",
"terminal.integrated.fontSize": 16,
"terminal.external.linuxExec": "gnome-terminal",
"terminal.explorerKind": "external",

Edit: Oddly it seems to get blurrier to the middle of the terminal line, I had a colleague double check in-case my eyes were going bad:

@tick-rick has some great examples attached, I can attach some more if these were not enough.

Do you set window.zoomLevel?

[beaudoco]

Here is a screenshot of my terminal, It does seem to be getting worse the closer to the center of the screen it gets. The zoom level is set to 1.

I had my zoomlevel set to -1, it seems setting it to 0 fixes the blurryness, very odd.

This is expected, we can't guarantee non-blurriness in this case because there's a 1-off rounding error that I don't think is specced out as browser zoom is not a web platform feature.
