[Bug 676413] [NEW] Video playback performance drops substantially after suspend/wake cycle (Lenovo X201 i5 w/ Intel GMA HD)

 

Public bug reported:

Binary package hint: xserver-xorg-video-intel

Note: I'm not 100% sure that this issue is with the driver, but it's my
best guess and I figured it would include the most relevant diagnostic
info.

I'm using Ubuntu 10.10 32-bit on a Lenovo X201 (i5, Intel GMA HD
graphics). When I first boot, video playback for Flash and HTML5 videos
in Chrome and Firefox is smooth. But if I suspend then wake up, it drops
noticeably. A few examples:

- HTML5 videos play smoothly after a reboot. Once I suspend/wake, they're choppy at best. Regular-sized videos seem to play fine regardless of size.
- Flash videos play smoothly (albeit with the usual Flash bugginess) after a reboot. Once I suspend/wake, they're *really* choppy on Chrome, and bring Firefox to its knees (it freezes for seconds at a time).

Playing videos in Movie Player doesn't seem to be affected by this, but
I'm not sure if this is just a result of it being so much more efficient
than the browsers that the performance drop isn't visible. Likewise, I'm
not sure if there's a qualitative difference between the full-screen and
regular-sized videos in Chrome and Firefox, or if the added load of
scaling the videos is making the performance hit noticeable.

I've tried both 64-bit and 32-bit 10.10, and both seem to suffer from
exactly the same problem. I don't recall this being an issue in 10.04--I
only used it for a month or so before 10.10 was released, but I think I
would have noticed this regardless.
