It hard to reproduce.Full screen switch or VT switch could reproduce this problem.
But in console:

** (deja-dup-monitor:2803): DEBUG: monitor.vala:263: Invalid next run date. Not scheduling a backup.

The problem is tested with the commit 6a574b5b9b with follow patches.
Jesse's kernel patches in this thread :
I'll try to reproduce this soon. It honestly just looks like Flash crashed for some reason, though...
Yes, I concur, this could be a Flash problem. However, more information would be needed. e.g. is this an x86_64 system? What's the version of gtk, nspluginwrapper and Flash Player?
Flash used to having focus and XEMBED problems in the past. This was a combination of Flash, Gtk, Firefox and nspluginwrapper bugs. It could be worth trying to reproduce either (i) without nspluginwrapper on a 32-bit platform, or (ii) with nspluginwrapper on a 32-bit platform. If this can be reproduced in both (i) and (ii) cases, then the most likely cause is Flash, and configuration (i) could make it easier to debug. e.g. attach the npviewer.bin process to gdb.
@Meng - does it still happens with 2011 Q3 version?
If it does, could you please try to isolate the problem as Gwenole suggested?
Meng has left our team. Jian, can you follow up?
I think this should exist in Q3 release. Let's try the latest code first.
On our IvyBridge(ivb2) with the newest unstable kernel(unstable_20110921+) and X package ,the video can be played well by firefox.
the video can be played well by firefox
