173934 - background goes black when viewing certain pages under Hummingbird eXceed X server

Status: RESOLVED INVALID

(SeaMonkey :: General, defect)

Description

[matt_hallam]

User-Agent:       Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.1) Gecko/20020827
Build Identifier: Mozilla/5.0 (X11; U; SunOS sun4u; en-US; rv:1.1) Gecko/20020827

When loading a "long" web page (ie where you have to scroll down several times),
typically with lots of text (the bugzilla "quips" page is just an example of a
long page that it happens on), then under Hummingbird's eXceed X server, the
background goes black. This happens regardless of what bgcolor is set to in the
html, or what the default background color is set to in preferences.

Reproducible: Sometimes

Steps to Reproduce:
1.fire up mozilla under solaris, displaying to an eXceed X server
2.browse to http://bugzilla.mozilla.org/quips.cgi?action=show  (for example)
3.what for page to finish loading, scroll down

Actual Results:  
background colour of page goes black (seems to be a redrawing problem)

Expected Results:  
background should have stayed as the html or preferences describe

This is most likely a problem with the Hummingbird X server. I've seen
several programs not behaving properly on their X server. Please check 
your X settings on your PC

The bug poster mentioned Solaris and eXceed being a problem. I use Redhat 7.x and
this is also an issue for me. I have tried tuning eXceed but have not been able
to reduce/eliminate the symptoms.

Which version of Exceed are you using?  I'm using 8.0 and have not been able to
reproduce the problem.

Can you give a new example of a mis-displayed page, as the referenced URL is now
very short.

Comment 4

[matt_hallam]

The bug affected versions 5, 6 and 7 of eXceed. Ive now just installed version 8
and the problem is still there :(

A new example of a misdisplayed page can be found at :

[Josh Birnbaum]

Okay, the problem is readily apparent with that URL.  Marking New

This doesn't look like bug 192795, though I initially hoped it was related. 
cc:ing blizzard (owner of that bug) to see if he knows what to make of this.

You might want to ask Hummingbird support if they have any ideas.

Attachment: Script that generates a sample HTML file to reproduce problem.

I was able to use the attached, fairly trivial shell script to generate a
sample HTML file that will reproduce the problem on my system using Netscape
7.0. (The Mozilla scroll-down black background when viewed in Hummingbird
eXceed.) When the value of LINES is set to 2183, the problem does not occur.
YMMV?

[Erwin Waterlander]

I have also problems with this bug. With all versions of mozilla running on
HP-UX. I used Exceed 6.2 and 8.0. Is this realy an Exceed problem? When I use
Netscape 4.79 this problen does not exist.

Erwin

reproduced here (indeed, it has been for some considerable time - I just haven't
been annoyed enough to search bugzilla until now).

This (as I type) is eXceed 7.1.0.0 on W2K SP3 displaying Mozilla/5.0 (X11; U;
SunOS sun4u; en-US; rv:1.5b) Gecko/20030713 in 24-bit colour, full screen, but
it has happened with older versions of both Moz and eXceed.

Further... My setup breaks at 2047 lines using Bob Hall's script; if it had
broken at 2048, I'd have been *really* suspicious :)

Hi,

I reported this bug to my system administrator also. He asked Hummingbird.
Hummingbird is aware of this bug and they fixed it in Exceed 8.0.0.17.
Now I'm running Exceed 8.0.0.17 and the problem is gone.

kind regards,

Erwin

Hummingbird said that the problem was fixed in 8.0.0.11, 7.1.1.15, and 7.0.0.23.
I tried the browser on eXceed version 7.1.1.16, but the problem still occurs. So
I'm still unclear whether this has been fixed or not.

Comment 12

[Josh Birnbaum]

Testing on my WinXP box, I have confirmed that exceed.exe version 8.0.0.17 fixes
the problem.  I am marking this bug "invalid" in that there is no Mozilla bug to
fix (rather, it was a Hummingbird Exceed problem that has been fixed).

Bob, regarding 7.1.1.16, not sure what to tell you.  I would recommend
contacting Hummingbird support again to see if they have any additional info on
fixing this with 7.1.1.x.  Or maybe try 7.1.1.17.  As for 7.0.0.23, I don't even
see that version listed on their site (just .22)

Lastly, to save others a search, the latest patches are listed on
http://www.hummingbird.com/support/nc/exceed_patches_prod.html

Comment 13

[matt_hallam]

as the original bug reporter, im just adding this to confirm that eXceed
8.0.0.17 does indeed fix the problem

Comment 14

[Bob Hall]

It looks like 8.0.0.17 does not fix the problem on our site. So either I'm
experiencing a completely different problem with the same symptoms, or there is
some specific configuration that solves the problem which we're not using. Oh
well, I'm not quite sure what to do at this point.

Comment 15

[Bob Hall]

We now have a fix for this on our site. First the Hummingbird eXceed product was
patched to  7.1.1.26. Next the "Allow Old X11 Bugs" option was disabled in the
Xconfig Protocol configuration dialog. Thereafter Mozilla displays pages without
the black background.
