(Camino Graveyard :: HTML Form Controls, defect)

Description

User-Agent:       Mozilla/5.0 (Macintosh; U; PPC Mac OS X Mach-O; en-US; rv:1.8b4) Gecko/20050802 Camino/0.9a2+

I have noticed that it is nearly impossible to write a posting on forums running
YaBB SE (http://www.medi-board.com for instance). Viewing the topics and logging
into an account is fine, but attempting to post a reply is causing serious
trouble. There is a significant latency between the keyboard input and the
result on screen, often interruped by beachballs. The same site mentioned above
is running perfectly with other browsers.

Reproducible: Always

Steps to Reproduce:
1.Go to a YaBBSe Forum like http://www.medi-board.com
2.Attempt to post a reply

Actual Results:  
Huge input latency, beachballs, performance issues all around!

Expected Results:  
Quickly respond to the keyboard input

Philippe, could you try the 0804 build and see if it's any better?  This is
probably another case of bug 301774.

Comment 2

[Wevah (Nate Weaver)]

Most likely. (Fixing summary.)

Comment 3

[Philippe Fthenakis]

I have tried it with 08.04 and if fixed the isuue for about 90%. Beachballs have
disappeared, but there is still some slight input latency, but it has become
much better too.

90% of what?

There are still other things that can be done to further improve the text field
experience.  See the dependencies on the bug I referenced.

You need to register to post on the site you cited.  Could you provide a more
accessible test case?

Are you noticing something wrong on that site in particular with the 0804 or
0805 build that you don't see in other textareas?  For example,
https://bugzilla.mozilla.org/attachment.cgi?id=178892 .

With image.animation_mode set to once, it's useable but still a little laggy
(probably our friend the caret); with i.a_m set to normal, Camino 20050808
essentially hangs for me (1.33 GHz G4), sucking 85-95% CPU. Sample coming.  May
well be our other perf bugs, though.

There's quite a bit of tiling happen here. Try with this build:

http://www.smfr.org/downloads/camino/Camino_20050808_quartz_tiling.zip

and let me know how it is.

I have also experienced this problem, with the message board at
www.sweetaddy.com, which use vBulletin. The Camino_20050808_quartz_tiling.zip
build successfully fixed it.

The tiling build seems to have *greatly* improved performance on the URL in the
URL field.  Responsiveness with animation enabled in the tiling build (50-75%
CPU) matches the perf *without* animation in normal nightlies, and
responsiveness with animation disabled in the tiling build is smooth (10-15% CPU).

So is all that's left here bug 166932 (by way of 280982)?  When I have animated images turned off, typing is not a problem.

Dupe or depends?
