Created attachment 340568 [details] Simple testcase to reproduce the issue If you open the attached test case and move the mouse over the blurred red square, the color changes to blue. But since the repainting bounds do not take into account the blur, the outer part of the blurred area stays red. After switching between windows (enforcing a full repaint), the blurred square is displayed correctly. This may be related to (or a duplicate of) https://bugs.webkit.org/show_bug.cgi?id=166739

Experiencing the same bug, https://codepen.io/Hectorplata/pen/PoGOqNq In this example I'm using css transitions to change the fill of an SVG with a blur filter and the bounds works well, but the exterior remains stationary causing a weird effect.

Confirmed this affects Safari 15.5+. Works properly in Chrome and Firefox.
