Summary [iOS] Corrupted rendering with brightness filter

Created attachment 351265 [details] Test case Steps to reproduce: 1) Open the attached page, zoom in and scroll. 2) Open a new tab. 3) Go back to the first tab and scroll. 4) Observe that parts of the page are rendered in seemingly-random positions. Sometimes steps (2) and (3) need to be repeated a few times. I've only managed to reproduce this on-device (iPhone 7 and iPhone XS), not in the simulator. This was originally reported as a Chrome for iOS bug (https://bugs.chromium.org/p/chromium/issues/detail?id=885323), but it reproduces in Safari as well.

Possibly a dup of bug 183271.

I can't reproduce this anymore (on iOS 13.3.1).

This was fixed in an OS change.
