Post-processing effect gets messed up when resizing viewport

Development Rendering

I was making an edge highlighting effect, and it works (freshly opened editor):

But when the viewport (or any other 3d viewport, actually) is resized to a smaller size, the post processing effect (only) is “shrunk” in proportion to how much smaller the new viewport is than the largest it’s been:

(For example, if the viewport was initially 1000x1000 when everything worked, then gets resized to 500x400, the green outline is rendered on the top-left 250x200 of the new 500x500 viewport.)

I am utterly stumped. Help, please?
