[Bug 201487] [NEW] Firefox uses the wrong DPI

[Alexander Jones]

Public bug reported:

Binary package hint: firefox-3.0

I noticed that the text on my homepage was larger than it used to be:
http://alex.weej.com/

After double-checking my source code (and finding that the font should
be 10pt high), I checked to see what would happen if I set the DPI
manually to that of my screen. In about:config I changed layout.css.dpi
from -1 (automatic?) to 96, and this caused the text to be drawn at the
right size.

Firefox is apparently checking the DPI settings for my screen
automatically. xdpyinfo reports my screen as being:

screen #0:
  dimensions:    1280x1024 pixels (300x230 millimeters)
  resolution:    108x113 dots per inch

Which is a bug in X also introduced this cycle.

Firefox should use the GNOME DPI setting when its own DPI setting is
"automatic" (-1). This value  currently resides in GConf under
/desktop/gnome/font_rendering/dpi.

This also affects Epiphany, which is how I found the problem in the
first place.
