Nightly 59 x64 20171128100440 de_DE 5b33b070378ae0806bed0b5e5e34de429a29e7db @ Debian Testing (KDE, Radeon RX480)
fresh profile: layers.acceleration.force-enabled, gfx.webrender.enabled, gfx.webrender.blob-images, image.mem.shared

It's correct during scrolling by mouse wheel, otherwise still broken.

(I realize WR is on in Nightly but there's no plan to let it ride in 59)

This appears to be fixed, can you confirm? It was likely fixed by bug 1419820 as Jan suggested it would be in comment 3.
