1115458 - On FirefoxOS Settings app would show outdated or black blocks when transitioning is ongoing

Status: RESOLVED DUPLICATE of bug 1114731

(Core :: Graphics, defect)

Description

[Greg Weng [:snowmantw][:gweng][:λ]]

STR:

1. Launch Settings app
2. "Screen Lock" -> set passcode

As video you can see there are some black blocks that renders so weird. If you turn the FPS on you can even see the black blocks show the outdated "buffers" as the second video shows.
