[Bug 317243] [NEW] [x86_64] Flash (sometimes) shows only white window when playing youtube videos

[Bryce Harrington]

Public bug reported:

Binary package hint: flashplugin-nonfree

[Problem]
Flash movies (e.g. youtube and youtube-like sites) seem to begin playing but instead show a blank white window.

[Steps to Reproduce]
1.  Boot up Ubuntu
2.  Start a music player (I used audacious) in the background
3.  Start firefox, navigate to youtube.com or similar site
4.  Select any video, load it and play
5.  A progress bar will flash, and then window immediately turns white
6.  Exit music player
7.  Reloading the page and re-playing video has no effect
9.  With music player off, repeat steps 3-4; this time video should play

[Discussion]
I'm not 100% sure I've got the reproduction steps exactly right in the above, however I've noticed a strong correlation between having the music player up and seeing the flash player break.

I recently also noticed a number of stray /tmp/flash* cruft when firefox
was not loaded, but have not yet definitively associated their presence
with one of these failures.  I've also noticed some mentions of
nsviewer.bin crashes in dmesg; again not definitively associated with
these whitescreen events, but seem suspicious.

I've had a number of problems in jaunty relating to pulseaudio, so my
guess would be that flash is hanging when other things are using the
pulseaudio system.

[System environment]
ubuntu:  Jaunty (development version)
linux: 2.6.28-4-generic #10-Ubuntu SMP x86_64
