Details

Description:
There are some vertical thin lines on the screen, when the page is zoomed (and I zoom in almost every page because of my wide-screen monitor).
I'm not quite sure if the bug is in packaging or upstream because the same bug occurs under suse 11.2. This is the bug report I've already filed on Novel bugzilla.
https://bugzilla.novell.com/show_bug.cgi?id=538989
There are screenshots also.

However, I have found the bug only under Suse and Arch Linux so far.

Additional info:
* package version(s)
* config and/or log files etc.

Version : 3.5.3-1


Steps to reproduce:
Zoom-in some web-pages (ex. http://www.google.bg/firefox)
This task depends upon

Works very fine for me. Maybe you have an issue with your video drivers/hardware/xorg settings/desktop enviroment settings/ combination.

(No problems here with nvidia-propietary + 7300GT + xorgs defaults + kde with composite and some effects)

Ati Mobility X1600, open-source radeon 6.12.4 driver in use.
I'll attach my "xorg.0.log" file.

This is my "Xorg.0.log" file.

About the desktop environment settings I cannot say much because under Arch you take the most part of the decisions but under Suse 11.2 the bug is present even when absolutely every detail from the installation process to the first start of KDE 4.3.1 is by defaults.

So I guess that is unrelated with firefox. Neither a packaging issue. My suggest is: report to upstream (not in Suse bugzilla), report to Radeon bugtracker, and in last case to bugzilla of mozilla.

Try in plain xorg, without kde, starting the default twm.

Status ? Can it be closed ?

Nope. The bug is still 'very' present indeed.
Comment by Jan de Groot (JGC) - Sunday, 07 February 2010, 23:14 GMT
Please file a bug upstream. In fact, this is not a really avoidable bug in the way firefox renders images. The google page you quoted contains several images put next together. When you start zooming, firefox will zoom each image individually. This causes white lines, as not every picture can be zoomed to a pixel boundary. If the size is rounded down in both images, you'll get a white line, if the size is rounded up, you'll get overlapping pictures. The only way to change this is to use zooming on viewport level, but this isn't implemented in firefox.
