Re: gtk_icon_theme_load_icon and GDK_SCALE=2 results in blurry icon

It looks like GDK_SCALE makes GtkIconView scale its icons (the pixbufs).

Glib::RefPtr<Gdk::Pixbuf> hd_icon = default_icon_theme->load_icon("gtk-harddisk", 64, 2, 
This makes a pixbuf of size 128 (the filename points to 128-size png).

However, when this pixbuf is set on a GtkIconView, it's scaled by it,
making the size 256.

Basically, I need a method of disabling GtkIconView's scaling of icons.

Have you tried

Yes I have tried gtk_icon_theme_lookup_icon_for_scale().
Passing size=64 and scale=2 to this function results in a blurry icon
of size 256. It seems the icon is scaled twice - once by "scale" and
more by GDK_SCALE=2.
Passing scale=1 gets me a blurry 128-size icon.

There you will find a reference to

where notes about displays with high pixel densities exists.

I guess you meant gtk_icon_theme_lookup_icon(). It just says to use
gtk_icon_theme_lookup_icon_for_scale(), which gets me a blurry icon.
