Status: RESOLVED WONTFIX

(Core :: Graphics: Layers, defect)

Description

[(No longer employed by Mozilla) Aaron Klotz]

I'm filing under Graphics: Layers since it looks like compositor problems and I can't reproduce it locally on native hardware.

STR:

1. Install Nightly and Flash on a Hyper-V VM running Windows 8.1. (You might be able to just install it on a remote Windows machine and connect with Remote Desktop, but I haven't tried that.)
2. Disable e10s on Nightly.
3. Go into Facebook and launch Candy Crush Saga (sorry).
4. Let the game load.
5. Observe Firefox CPU usage. Eventually black boxes begin appearing until you can't see anything.

Not really sure what priority to give to this one; we are using CPU for both painting and compositing, so I would expect the load to go up, but I wouldn't expect correctness issues.

Aaron, what happens if you set layers.d3d11.disable-warp to true?

After closing the Candy Crush tab the CPU usage eventually settled down, so that must be a red herring

Same problem.
