See attached screenshot. If I remove the:

:root {
  filter: var(--retropx-brighten, none);
}

declaration, then it renders ok (slow, but ok). That's effectively just filter: brightness(1.5).

The website looks fine in a couple versions of Safari that I tried, including STP 144.

I see, maybe this should be moved to a GTK specific component. Not sure which one is better tho, thoughts?

Disabling AC mode (WEBKIT_DISABLE_COMPOSITING_MODE=1) can work around the issue.
FWIW, WinCairo WK1 and WK2 don't have this issue even in AC mode.
