Actually this can be reproduced by visiting any site that is not in history.

(Can't seem to reproduce in Windows, -safe-mode, or not understanding.)

Can you attach a screenshot?

I can't because the bookmark bar returns to normal when I try to take a screenshot.

I mean that the text of bookmarks in the bar appears darker than usual. That's what I meant with 'multiple times' - those renditions are stacked on each other.

Attachment: Screenshot taken with my digital camera

This screenshot shows the artifacts that I mean. Note that the "Nordea" bookmark, for example, is much bolder than the other ones. Again, this does not happen every time.

Hmm. Does this happen with SeaMonkey 2.3?

Yes, it does. Not always, but from time to time.

In Firefox 6 we’ve added the ability to alter prefs that affect the underlying ClearType subpixel anti-aliasing that is used:

gfx.font_rendering.cleartype_params.cleartype_level
gfx.font_rendering.cleartype_params.gamma
gfx.font_rendering.cleartype_params.enhanced_contrast
gfx.font_rendering.cleartype_params.pixel_structure
gfx.font_rendering.cleartype_params.rendering_mode

These are effectively local overrides of ClearType registry settings that are set by running the ClearType tuner tool (Control Panels > Fonts > ClearType Text Settings). You can alter the values here and only text rendering in Firefox will be affected. These parameters allow you to adjust the contrast and switch the rendering mode. By default Firefox uses DirectWrite natural rendering mode (4) for small text and DirectWrite natural symmetric mode (5) for larger text. Use GDI Classic rendering mode (2) to render text the same way Firefox 3.6 and Chrome render text.

Try changing the settings from -1 to 2 (GDI Classic)

I tried changing the settings (I had to manually create them), but it didn't help.

Does something change in newer SeaMonkey versions?

Comment 11

[Phoenix]

Aki?

Comment 12

[Aki Laaksovirta]

No, nothing has changed in, for example, SeaMonkey 2.11 on SuSE 12.1. I created gfx.font_rendering.cleartype_params.rendering_mode and set it to 2. Let's see if that helps.

Comment 13

[Phoenix]

So, is it helps?

Comment 14

[Aki Laaksovirta]

No. The issue still happens.

Comment 15

[Phoenix]

Okay, can you check, is this happens also in Firefox?

Never reproduced,  no answer of reporter, so I close this one.

@Reporter: Please feel free to reopen this Bug if you still can reproduce with a current SeaMonkey version and a current OS.
