Problem displaying pages deep into Facebook

[Roger Davis]

After I have been using Facebook for an hour or more, SeaMonkey freezes up. The display won't advance, pictures may overlap, becomes generally unresponsive, sometime with a really messed up display.

I know it's in SeaMonkey, as Chrome has no such problem.

Cache has been at 500, recently upped to 1000. I've tried both fixed and "let SeaMonkey" manage it.

This is costing me about an hour a day. How can I fix it?

Ha! So, I'm not alone with such a problem. No, I'm not using Facebook.

Since update to SeaMonkey 2.40 I'm experiencing problems with pages pictures heavy (especially GIFs). Any pages. I thought it was problem with my AV (Eset NOD32, latest) and/or firewall soft (Agnitum OFP). I was trying to disable them or make exceptions for seamonkey.exe but without positive result. I thought it was problem with some extensions:

... but it was just some mistake.
Reverting to older Nvidia drivers didn't help too.

I'm starting SeaMonkey with Mail&Newsgroup client. First I'm downloading e-mails. Since SM 2.40 I'm noticing some problems with icon of messages (both old and incoming new) - some didn't appear until I'll move mouse cursor over them.

In Browser, when browsing sites pictures heavy, I'm experiencing lags and short freezes (for half a second, second, few seconds, depends on site). I'm browsing in tabs (usually in one window). When SM freezes I can't do anything with any SM window (Task Manager shows 100% per one core; SM is "single core" so far). I thought it was problem because of my slow internet access but no - SeaMonkey 2.40 can freeze while displaying already downloaded pictures (especially bigger GIFs).

For a test I've uninstalled SM 2.40 (completely and then restart of PC) and installed SeaMonkey 2.39... and problem disappeared. Pages were loaded/displayed like before - if picture was big and not completely downloaded (including GIFs) then I was still able to browse such site and switch between tabs/windows.

It must be something with 2.40 version. Maybe switching to newer (but not latest) VC++ made this problem? Most of my computer are old and equipped with Intel Core2Duo CPUs (E8400). AFAIK newer runtimes prefers multicore processors (like i5 or i7) and in some rare cases older C2D will have problems.
I saw this with PC games but then BES helped for this:

... but not for SeaMonkey (at least not much).

I've installed SM 2.40 again because of security reasons - I'd rather suffer of lags and freezes then use vulnerable software.

Are there any other users with Intel C2D CPUs who experienced similar behavior of SeaMonkey 2.40?

EDIT: I'm using RAM disk so access to cache is really fast.

Adrian just compiled 2.43. You might try this one and see if the problems go away. It's not official but the next best thing until 2.43 hopefully arrives soon:

https://l10n.mozilla-community.org/~aka ... windows32/

2.40 like 2.39 was compiled using VC++ 2013. The runtime didn't change. 2.46 is the first version which will use VC++ 2015.

From memory I had some connection and image problems in a local compiled 2.40 too. 2.41 was stable and 2.42 really good. There were lots of changes in the mozilla code in these releases which might have caused this.

Btw. I am also using Seamonkey on an old L9400 Core2Duo laptop with lousy Intel graphics drivers without problems. VS2015 x64 build locally compiled and it's stable there. Flash (which I do not have installed), antivirus software and some addons seem to cause the most problems these days.

After I have been using Facebook for an hour or more, SeaMonkey freezes up

How much memory & CPU is SeaMonkey using at that point?

Since SM 2.40 I'm noticing some problems with icon of messages (both old and incoming new) - some didn't appear until I'll move mouse cursor over them.

Might try Safe Mode, or as a test, a new clean Profile (as some Pref settings may no longer be [as] compatible as they might have been with SeaMonkey < 2.40).

For the first time in ages, I had my Screen Goes Black. (I didn't fully freeze, & was able to successfully Quit [blindly], but its been quite a while since I've run into anything like that. And yes, using 2.40. Could have been coincidence - or not?)

Tried it and no go. I mean at the beginning in safe mode it looked like "better" but after some time it was the same as usual. All plugins are set to "ask to activate".

"Important Locked Preferences": none

I tried to change some "gfx" preferences (especially with D3D and D2D) but without positive results. D2D, hardware acceleration and font smoothing was disabled because of problem with "Clear Type" under Windows 7.

Found solution - maybe.

Set cache to 1000, DO NOT let SeaMonkey Manage, restart.

So far, so good, but I haven't put it to severe test yet.

Word "maybe" was good choice. The same effect you'll have by clearing cache - first few pages loads a little better but soon or later the same lags/freezes will come back.

IMHO it's not about size of cache. I'm experiencing problems with displaying pages with GIF files already downloaded. And problems (longer freezes) will occur when GIF is "one PageDown (full display mouse scroll)" below current displayed content. To make it clear (my English grammar is awful): SeaMonkey will freeze on some pages when GIF (or bigger picture) is not displayed already but is "prepared" for display on next PageDown (or mouse scroll).

Older SeaMonkey 2.39 works correct in that matter. I didn't tested unofficial builds because problems could be caused by "build machine". I'll wait for next official build (at least beta version).
