(The problem was experienced with Linux Libertine and mkiv, and not with Latin Modern.) The workarounds are: * Put the overstriked text in a <code>\inframed[frame=off]{}</code>. Example:<texcode>\setupalign[hanging,hz]bla bla bla \inframed[frame=off]{\overstrike{striked}} bla bla</texcode> * Turn off microtypography for the paragraph containing the overstrike.
