Seem to relate to bug 163427. Disable compositing mode with WEBKIT_DISABLE_COMPOSITING_MODE=1 works.

Once that bug gets fixed, please test with a new version of GTK+ with that fix. If it's still broken, then we can reopen this issue.

Um, I guess I read the bug name and not the actual description, sorry. This must indeed be a WebKit bug.
