We don't have support for windowed mode yet. Marking dependent on that work.

Ever confirmed: true
If you set |plugins.force.wmode| to transparent in a non-e10s build, do you see similar behavior? If so this is just a side effect of flash windowless mode not being very efficient. If it *doesn't* repro outside e10s mode with that pref, though, it could mean our plugin layers code needs to be looked at for windowless, which is probably independent of the windowed-mode/IPC work
Component: Video/Audio → Flash (Adobe)
Product: Core → Plugins
Version: 32 Branch → unspecified
Note, I'm not seeing a big improvement in perf with windowed plugins either. This may be more internal vs. something related to windowless.
I'm marking this invalid simply because I can't find flash on youtube anymore. Please reopen if you can reproduce on another flash based video site.
