Hi, Blender is limited here because of it support very old hardware.
This will change with Blender 2.8.
You can try different Window Draw Methode and change Image Draw Methode to GLSL in User Preferences > System.
Uncheck MipMaps can may help too.
You have to restart Blender after change a setting.
