Comment 24 for bug 1500282

(In reply to Panos Astithas [:past] from comment #20)

Not as is, but I'd be happy to take a patch for a 1.5 step, even though Mac
and GTK do not, because, at that level, I expect the benefits start to
out-weigh the flaws, and WINNT does this.

Would that help your situation?
What are your Gdk/WindowScalingFactor and DPI values?

The DPI from GDK is a font scaling dpi. Users do not expect small changes to
trigger blurry icons and UI, ugly tabs, etc.

Also, Gecko does not provide a good way for authors to supply pixel-accurate
bitmaps at arbitrary sizes.
