Created attachment 463303 [details] example of filter redraw bug If a filter property has already been applied to an element, applying a new filter (by hovering, for example) does not redraw the element with the new filter. See the attached example. Works fine in Chrome/Firefox. Broken in Safari. **This is a regression from Safari 16.0** macOS 13.0 Safari 16.1 (18614.2.9.1.12)

Weirdly this works if you have layer borders visible (maybe the repaint counter triggers a repaint).

works: r292363 fails: r292367 r292364 ([GPU Process] CSSFilter should be created only at the painting time https://github.com/WebKit/WebKit/commit/19c9835a3ebfadc9066e174716c63359bb8e7bb0 ) is a strong candidate.

We're repainting correctly, but some cached filter state is stale.
