449094 - UI does not scale at DPI settings lower than 144.

Status: RESOLVED DUPLICATE of bug 426788

(Firefox :: Menus, defect)

Description

[Jimbo Jones]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.0.1) Gecko/2008070208 Firefox/3.0.1

I recently upgraded to FF3. In FF2, all elements of the UI scaled to reflect Windows' DPI setting. I discovered it has no effect after upgrading to FF3, however. The menus at 96 DPI are the same size as at my DPI setting (130 DPI). Upon further investigation, changing the setting "layout.css.dpi" in about:config does have an effect, but only at DPIs equal to or greater than 144. You can see how this is problematic.

Reproducible: Always

Steps to Reproduce:
1. Install FF3.
2. Change Windows DPI setting to anything other than the default, but less than 144 DPI.
3. Change the setting "layout.css.dpi" to anything less than 144 DPI.
Actual Results:  
UI not scaled to reflect Windows DPI (or config setting).

Expected Results:  
Scaled up (or down) UI so that it reflects the change in DPI from the default of 96.
