Flash video freezes (not a FF or plugin crash, looks like overlay)

Bug #282020 reported by jaduncan on 2008-10-12
Affects Status Importance Assigned to Milestone
flashplugin-nonfree (Ubuntu)

Bug Description

Binary package hint: flashplugin-nonfree

When playing videos on flashplugin-nonfree they periodically (1-2 mins in to a video generally, but fairly randomly) stop updating the video while the sound plays on perfectly. On moving the window, the video immediately pops back and updates (to perfectly in sync with the sound). This can also be caused by moving the web page within the window, moving another window partly over the video image or positioning a right click menu so it pops up over the video image. This feels like a video overlay bug, but only occurs with flash. Totem plugin works perfectly for hours of video playback, and so does mplayer. Swfdec also does not display this behavior, even on the same files.

My machine is an x61s Thinkpad with an x3100 video card. The video card is running on the intel driver, and compiz is not enabled.

Software versions are Intrepid as of 12/10/08, and the relevant packages are: flashplugin-nonfree (, xorg-xserver (1:7.4~2ubuntu7) and xorg-xserver-video-intel (2:2.4.1-1ubuntu6).

The xorg.conf file is autogenerated, but included as an attachment for completeness.

I am available for followup, and I am willing to test any binaries or patches.

Many thanks.

I have exactly the same problem with intrepid on easynote-bg45. My graphics card:
00:02.0 VGA compatible controller: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03)

Enabling compiz (in appereance->Visual effects) workarounds the problem.

Changed in flashplugin-nonfree:
status: New → Confirmed

Exactly the same problem appears in frozen-bubble and mplayer if using -vo x11. So it's probably a bug of xorg-x11 and it also makes it critical

This bug seems to be gone with latest update. Needs to be confirmed

Sorry. The problem is persisting. However I discovered that it happens only after suspend/resume. Restarting X-server doesn't help. Additionally suspend/resuming before login doesn't create this problem. I suppose the difference is that before the login suspendin is done by acpi-support and after login with gpm. Will diagnose further and report back tomorrow

The problem on flash player 10 still occurs for me.

If devs want extra information on this, I can provide it on request.
