For example with https://webkit.org/blog/12445/new-webkit-features-in-safari-15-4/ With GTK3 or WEBKIT_NICOSIA_PAINTING_THREADS=0 it works fine.

Seems to be caused by `filter: brightness(1)` on the `.preserve-color` class. In fact, all elements with any CSS filter applied seem to be invisible. For example, on https://developer.mozilla.org/en-US/docs/Web/CSS/filter. Almost all of the examples show up blank. The exceptions are the two "SVG equivalents" of `drop-shadow()`, which do show up but apparently without any filter effect. With GTK 3 or WEBKIT_NICOSIA_PAINTING_THREADS=0 everything works as expected.
