When in mission control on macOS (zooms out to show all open application windows) I frequently see Firefox look like its UI is made up of multiple boxes. It's a bit hard to explain so see the screenshot attached.
It generally only happens when Firefox has focus when entering mission control. It happens regardless of whether webrender is on or not, though with webrender there seem to be less boxes. I don't see this with any other apps and have been seeing it for some time.
Running current Nightly on macOS 11.1

Maybe we can set CALayer antialiasing flags to avoid this.

We currently don't ever set non-rectilinear transforms on our CALayers, so there
is no need for anti-aliasing. Explicitly disabling edge anti-aliasing means that
there are no seams between tiles when the window server draws our window with a
transform, such as during Mission Control.
