adjective

buggy

BUG-ee/bˈʌɡi/

Containing errors that cause software to work incorrectly.

The buggy software displays overlapping windows and broken images.

A middle-aged white man encounters visibly malfunctioning software on a laptop: overlapping blank dialog boxes, a broken image placeholder, and misaligned interface elements make the defects concrete without written error messages.
Etymology

Buggy originally meant infested with insects. The later use of bug for a mechanical defect—perhaps imagining an insect in the works—makes buggy software figuratively full of troublesome faults.
