The layout becomes blurry when the page is scrolled down/up
Spin off of https://webcompat.com/issues/17359 1. Navigate to https://es.m.wikipedia.org/wiki/Anexo:Pa%C3%ADses_por_%C3%ADndice_de_desarrollo_humano 2. Scroll down the page. 3. Observe the page layout. **Expected Behavior:** The page is fully visible. **Actual Behavior:** Some section of the page is blurred. **Note:** 1. Also reproducible when scrolling up the page. 2. Reproducible on Firefox 60.0.2 Release. 3. Not reproducible on Chrome 67.0.3396.87. 4. Screenshot attached. **Watchers:** @softvision-sergiulogigan @softvision-oana-arbuzov sv; country: es https://webcompat.com/uploads/2018/6/022baf2d-ccab-4390-b737-0eaafa67ffea.jpeg To note that this happens on Firefox Android only and it seems related a rendering issue after scrolling. Even accentuated on fast scrolling.
This seems to be caused by the same cause of bug 1469731. And smells a bug in graphics backend for Android.

I can see this on my old Android phone (android 4.4.). I highly suspect this is an APZ issue. I guess the map image on the site is pretty heavy?
Component: Layout → Graphics
Does the blurry rendering persist, or does it go away after a couple of seconds? When I tried it, it went away after a couple of seconds, so that seems like it's just slow rendering. If it persists then it's a more severe problem because it means we aren't requesting the correct displayport.
Component: Graphics → Panning and Zooming
It goes away after a couple of seconds.
