126122 - artifacts with fonts rendering

Status: RESOLVED DUPLICATE of bug 112673

(Core :: Layout, defect)

Description

From Bugzilla Helper:

BuildID:    2002021423

I've noticed this bug somewhere in 0.9.7+ series

Fonts are rendered sometimes incorrectly and it seems to depend on 'display
resolution' setting. In my case, this artifact appears when i set 'display
resolution'='System setting', which happens to be 100dpi.

This is not X-driver specific bug, i had it on XFree 4.0.1 with nvidia drivers
and XFree 4.1 with mga drivers.

I found something similiar in bug 45838.

I will attach screenshot.

PS: I am trying to get it now and can't get it. I have crazy idea that it
disappeared after switching 'Display resolution' back and forth.

Reproducible: Sometimes
Steps to Reproduce:
1. run X -dpi 100
2. run moz, go to prefs, set 'display resolution'='System setting', restart moz.
3. go to some text&href rich website, like slashdot.org
4. try scrolling around, look for bad font rendering
4.1 try selecting blocks of text -- you should notice it shifting 
    couple of pixels left or right

In my 'fonts' pref page i have following settings:

'Proportional'='Sans Serif'
'Size'='12'
'Sans-serif'='microsoft-verdana...'
'Allow documents to use other fonts'='No'

yes, this is true-type font, rendered with freetype-2.0.8 lib.

Never saw this bug myself (linux)
Try setting display-resolution in mozilla prefs to 96.
