Created attachment 465936 [details] Screencast Since 2.41.2, images flicker on cnn.com. See attached video. This is different from bug #253807 because (a) I have not manually upranked gst-va, and (b) this did not occur prior to 2.41.2.

OK, it's not just images. Another screenshot attached: this time, a chunk of the headlines are flickering.

I can no longer reproduce this today, after reverting the change from bug #255082. It seems truly incredible that this flickering could be caused by a font size calculation change, but the bug was pretty severe yesterday and gone today, and there's been only one change, and we know it caused spectacular rendering errors on reddit to, so... there we have it.
