e10s is enabled dom.ipc.plugins.asyncdrawing.enabled is enabled STR: 1. Navigate to http://ja.y8.com/games/pirate_the_treasures_return 2. Let flash content load then scroll Expected: Flash Content is not effected by the scroll Actual: Flash Content is distorted by the scroll This is not reproducible when dom.ipc.plugins.asyncdrawing.enabled is disabled

Justin, what does the distorted Flash content look like? After I skip the ad and wait for the Flash game to load, I can scroll the page without any visual distortion. I'm using 64-bit Nightly 54 on Windows 10. Maybe this is a problem just with 32-bit Nightly?

Here is a video of what I am seeing. https://jwilliams-softvision.tinytake.com/sf/MTM5NTU0MF81MDQzMDg0 I am using 64 bit firefox on a Windows 7 64 bit machine.

Thanks! That does look bad. The video made the problem very clear.

I cannot reproduce this with latest Nightly 55.0a1, 20170308030207 on Win 10 Surface Pro. STR's don't necessarily match what is being presented in comment #2 video. In the video, scrolling is taking place during game "Preparing," not during game play. I can't reproduce what has been reported in either case; game preparation phase nor in game play.

Thanks for this video. Seeing something like this is rather odd with windowless rendering. Regardless I don't think this blocks, it doesn't prevent game play. If the problem is more widespread (ads on popular news sites for example) we might. No reports like that have surfaced.

Are you seeing this in latest nightly?

No I can not Jim. It looks like this issue has been fixed.
