218590 - gtk call of gdk_flush hangs mozilla

Status: RESOLVED DUPLICATE of bug 136362

(Core Graveyard :: GFX: Gtk, defect)

Description

[Justin]

User-Agent:       Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.2.1) Gecko/20030225
Build Identifier: all versions

Using RH9, X ver 4.3.0, gtk+ 1.2.10

Browsing the web will randomly hang mozilla (though it will happen quickly). All
versions of mozilla do this, by all versions I mean all versions of binaries,
optimized builds, debug builds, and all firebirds.

Once I get a browser working on the box this is happening on will post a stack
trace.

Reproducible: Always

Steps to Reproduce:

gtk, not xlib

Comment 2

[Justin]

Attachment: first 80 frames on the stack

hopefully this is enough information. If not let me know and I will do my best
to provide anything else

Comment 3

[Justin]

I just rebuilt firebird to use gtk2 instead of gtk. Does the exact same thing.
So I am not certain where the problem is anymore.

Comment 4

[Christopher Blizzard (:blizzard)]

I've seen this hang before, but I can't remember exactly where.  It's buried in
a bug somewhere.  Are you stumbling across a site that has some asian text that
needs to be scaled?

Comment 5

[Justin]

Since it hangs before I really get to see whats on the page, there is a good
possiblity of that.  Especially, since its always in CSS rendering code too.

Comment 6

[Justin]

A good example of how to hang mozilla is:
http://www.cl.cam.ac.uk/~mgk25/unicode.html

simply scroll down a bit and it will hang

Comment 7

[Christopher Blizzard (:blizzard)]

You wouldn't happen to be using xinerama, would you?

Comment 8

[Justin]

yes. been using xinerama for a couple years now. and for the builds I do have
--enable-xinerama.

hmmm... will try it without --enable-xinerama.

Comment 9

[Christopher Blizzard (:blizzard)]

It's not the configure flag, it's using xinerama.  Try the normal build but
while not using xinerama on your X server.

Comment 10

[Justin]

it was xinerama. ugh that is not good.

is there any known solution to this problem? It use to work fine until I
upgraded from redhat8 to 9.

dupe of "using Xinerama and Xfs can hang the browser"
