Description Michael 2011-06-08 19:39:31 PDT

The dots on the chart will get stuck on the right hand side of the graph until the next data update.

Reproducible: Always

Steps to Reproduce:
1. Open
2. Allow the graph to load and tick a few times
3. Switch to another tab for ~15 seconds
4. Come back to the tab and note the position of the dots and line before the next update tick.

Actual Results:  
Dots all clumped on the right side of the graph.

Expected Results:  
Dots continuing to move with the line as they do when the tab is in the Foreground

Hardware acceleration is on.

Works as expected in Firefox 4.
Comment 3 Robert Longson 2011-06-09 00:30:37 PDT
or bug 586201 Does setting layout.throttled_frame_rate to 60 in about:config have any effect?

At first glance, looks like a likely duplicate of bug 647001... but I don't see why, given that the page seems to only use 1000ms timeouts.  Or is there a faster-running timeout on there somewhere?
Comment 5 Boris Zbarsky [:bz] (still a bit busy) 2011-06-09 01:20:08 PDT
jst, if we think this is something we need to fix for Fx5, I can try to write a quick patch for bug 647001 and see whether it helps...

Robert, that pref no longer does much of anything.
Comment 6 Daniel Holbert [:dholbert] 2011-06-09 09:09:59 PDT
Might also be related to bug 658189...
Comment 7 Boris Zbarsky [:bz] (still a bit busy) 2011-06-09 10:18:55 PDT
Unlikely; if I switch background tab setTimeout to a lower value (even 200ms is enough) the problem goes away.
Comment 8 Johnathan Nightingale [:johnath] 2011-06-13 14:29:35 PDT
Too late for 5, but since this will represent a regression in 5 so +'ng for tracking-6
Comment 9 Jesse Ruderman 2011-07-04 06:38:30 PDT
Fixed by bug 647001?
Comment 10 Michael 2011-07-04 09:33:10 PDT
The behavior is fixed in 7, I was still able to get it to occur once or twice in the 10 minutes that I tried. Nothing reproducible however.
Comment 11 Asa Dotzler [:asa] 2011-07-17 23:28:44 PDT
Are we going to try to do anything for 6 or are we calling this bug "done"?
Comment 12 Boris Zbarsky [:bz] (still a bit busy) 2011-07-18 07:04:57 PDT
I think we're calling this done....  The only fix here is to fix bug 647001, and that one wasn't approved for 6.

I have tested it on these builds of Aurora and Nightly, and the bug does not reproduce anymore.
Can I change the status to VERIFIED FIXED?

Setting resolution to verified Fixed on Mozilla/5.0 (Windows NT 6.1; rv:7.0) Gecko/20100101 Firefox/7.0

The dots are moving correctly.
