blurry view with magnification in Gnome

[Milton]

Hi List,

I use Ubuntu 14.04.3 with Orca 3.18 and installed gnome-shell for 
someone to work with magnification. I also installed 
compizconfig-settings-manager and compiz-plugins. Now I can toggle 
magnification on or off, zoom in and zoom out. The only thing left to be 
perfect is sharpness. The view is blurry. Did I miss something? Do you 
have tips for me? Thanks.
