PostPosted: Sun Sep 19, 2004 6:04 pm    Post subject: Firefox font corruption Reply with quote

When browsing large webpages with Firefox (for example a large forum post here), and I scroll around a bit, there are (pixel-) lines missing from the lines of text.

example
Some are marked in red, and if you look closely, you'll notice less visible font corruption in allmost every line. (note there's nothing wrong with the green ones)
When I focus another window, the fonts are restored

As far as I know, this problem has existed since before mozilla 1.0, and has kept me from switching away from Opera. Must be something with Gecko
Even Thunderbird seems to be infected

Has anyone else noticed this kind of font corruption besides me?
The problem is non-existant on Windows

some data:
- Firefox 1.0 pre
- X.org 6.8.0
- Everyting is rendered in the Bitstream vera fonts
- smooth scrolling is ON (but that doesn't seem to matter)
- default character set: ISO-8859-15

Did you set screen size in xorg.conf or pass custom dpi to startx?

No.

btw, enabling/disabling Composite doesn't help, just checked

Does selecting and then deselecting the corrupted text solve the problem?

Then I have the same problem as you - in both mozilla and firefox.

This happens to me too. Deselecting and reselecting fixes it. It's probably a bug in Gecko.

I always set the display resolution to 96 dpi (font preferences) to get rid of these missing pixel lines. You might have to restart firefox before this works.

are you talking about stating X like this:

Code:
startx -- -dpi 96


it sounds like you are saying there is a way to reset dpi while X is running, how does one do that?

No, he's talking about firefox (Edit -> Preferences -> Fonts & colors -> Display resolution)
