When brigning up a context menu, in firefox by a right click in a web page or the menu bar, the context menu take 2-3 second to appear, the same thing happens when clicking a drop down list.  This is specific to running Ubuntu Intrepid 8.10, in an LTSP (Linux Terminal Server Project) environment.  More information can be found in the URL provided.



Reproducible: Always

Steps to Reproduce:
1.Open Firefox on a Thin Client connected to an Ubuntu 8.10 Terminal Server running LTSP 5
2.Click File from the menu bar.
3.Or, Right click on in the window.
Actual Results:  
The menu or drop down will take 2-5 seconds to actually display after clicking.

Expected Results:  
Menus should display as quickly as possible the amount of lag discribed makes the program difficult to use.

Vlad, how much do we support/care about nonlocal X sessions?

Not a whole lot; patches accepted, of course.

regression range from bug 492353:
2007-12-18-04-trunk
2007-12-19-04-trunk

The pushlog doesn't show anything for these dates (too old maybe):

http://hg.mozilla.org/mozilla-central/pushloghtml?startdate=2007-12-18+04%3A00&enddate=2007-12-19+04%3A00

I used:
TZ=America/Los_Angeles hg log -d "2007-12-18 04:00 to 2007-12-19 04:00"

Looking at commit messages, this one mentions dropdown: bug 369599.

Hello,

I just did the following:

- downloaded 2007-12-19-04-trunk to an older SuSE 10.1 system
(this is comparable to SLES10, such its rather old)

Here the dropdrown menu is fast.

The same binary on the openSuSE 11.1 is slow (3 seconds before it opens)

(2007-12-18-04-trunk the one from the day before, is fast as usual)

==> the same binary 2007-12-19-04-trunk is slow on a new system,
but fast as usual on an old one.

Hello,

I found it :-)

Its not related to firefox but X11.(or the interoperation of both)

Not linking libX11 against libxcb does the trick.
Heres the reference which I found:

https://bugs.launchpad.net/libxcb/+bug/277069

They report the slow drop down box too.
So, maybe this bugreport should become a new bug with the
subject:

firefox is slow with libX11/libxcb dependency on remote X11

(as an example the dropdrown box can be used)

regards,

Martin

I believe this is caused by https://bugs.freedesktop.org/show_bug.cgi?id=17868 which is now fixed upstream. It's also finding its way into distributions, see https://bugs.launchpad.net/libxcb/+bug/277069

this should be WFM (or invalid) per the following.
if you disagree, please comment.

Jaunty reached end-of-life on 23 October 2010, so this bug will not be fixed in that version of Ubuntu. It has been fixed in newer versions.
