font display problem in mozilla
Rick Pasotto
last line of text in a mozilla display is only partially visible, then
scrolling up one line sometimes results in the characters being only
partially displayed. A page-up followed by a page-down to return to the
same place corrects it.
Is this an X problem or a mozilla problem?

I've seed this too, and I'm surprised that more people haven't
complained about it. Maybe it only happens for certain setups. Has
anyone else seen this?
It shows up in both mozilla and galeon. The problem isn't so much a
font display problem as it is a page display problem. After scrolling,
portions of web pages are offset by a pixel or two. It happens for both
images and text, though I find it more noticable with text. Sometimes it
happens after scrolling, but I've been paying attention to this for a
while and sometimes these display offsets happen on a freshly-drawn
page.
The screen captures at http://orr.falooley.org/pub/mozilla_bug/ show
what I'm talking about. These shots are from galeon 1.2.1. The mozilla
"about:" page says:
Mozilla 1.0 Release Candidate 2
Mozilla/5.0 Galeon/1.2.1 (X11; Linux i686; U;) Gecko/20020421
Debian/1.2.1-2
I've been hoping that each new release of mozilla would cure this since
I first saw it in 0.9.6 or so.
anyone?

Yeah, myself and a colleague at work have both seen it. It's an
off-by-one error in their rendering engine, but I'm not sure if it's
filed; I can never find my way around in Mozilla's bug tracking system.

Selecting the text also causes the display glitch to disappear, by the
way.

Yep, I've got it too :) :(
Has anybody filled a bug report?

I actually looked this up once; it was reported fixed in debian bug
#138788, which refers to bugzilla bug #83289. That "fix" didn't work,
though, or at least didn't address all the problems. I suppose #138788
should be reopened.

Yes. You can often see text jump by a few pixels when you select it;
however, the resulting position isn't always correct. You can also fix
the entire display by switching to another virtual desktop and back, and
you can sometimes see offsets change in galeon's display by moving
another window around on top of it.

Switching desktops or moving a window over your galeon/mozilla
window doesn't cause the browser to "re-render" the page.
Is this actually an X problem and not a galeon/mozilla one ??

My experience doesn't really match Mozilla bug #83289. I think it's
more related to Mozilla bug #63336, which unfortunately has been
targeted as "future."
FWIW, I think I started seeing this problem when I switched my X server
From=2075 dpi to 100 dpi. Of course, a lot of stuff happened at around
the same time, so it's hard to say. Does Mozilla use the X server's dpi
settings at all?

I added this line:
user_pref("browser.display.screen_resolution", 96);
to my .galeon/mozilla/galeon/prefs.js file, and it seems to have fixed
it. Maybe try fiddling around with the 96. (Mozilla has an entry in
the preferences dialog to change this, but Galeon doesn't.)

Positive result here - I did have it set to "system setting", and
flipping it to 96 has cured it for me.
Thanks.
