Software bug

bugsbugsoftware bugs
A glitch, which is slight and often temporary, differs from a more serious software bug which is a genuine functionality-breaking problem.
Problems with military gear during World War II were referred to as bugs (or glitches).

Race condition

race conditionsdata racerace
Generally, this implies an electrical pulse of short duration, often due to a race condition between two signals derived from a common source but with different delays.
Certain systems can tolerate such glitches but if this output functions as a clock signal for further systems that contain memory, for example, the system can rapidly depart from its designed behaviour (in effect, the temporary glitch becomes a permanent glitch).

Glitching

glitchglitchersgraphic glitches
"Glitching" is the practice of players exploiting faults in a video game's programming to achieve tasks that give them an unfair advantage in the game, over NPC's or other players, such as running through walls or defying the game's physics.
Glitching is an activity in which a person finds and exploits flaws or glitches in video games to achieve something that was not intended by the game designers.

Runt pulse

A related concept is the runt pulse, a pulse whose amplitude is smaller than the minimum level specified for correct operation, and a spike, a short pulse similar to a glitch but often caused by ringing or crosstalk.
asynchronous clocks; or as the result of a race condition in which a signal takes two separate paths through a circuit, which may have different delays, and is then recombined to form a glitch; or when the output of a flip-flop becomes metastable.

Speedrun

Heavy use of glitches are often used in performing a speedrun of a video game.
Many games have opportunities to disarrange the intended sequence of events and skip entire parts of it — often called sequence breaking — and many more have programming mistakes, or glitches, that a skillful player can exploit to their advantage.

Glitch removal

Glitch removal is the elimination of glitchesunnecessary signal transitions without functionalityfrom electronic circuits.

In a technical sense, a glitch is the unexpected result of a malfunction, especially occurring in software, video games, images, videos, audio, and other digital artefacts.

Invisible wall

invisible walls
Graphical glitches are especially notorious in platforming games, where malformed textures can directly affect gameplay (for example, by displaying a ground texture where the code calls for an area that should damage the character, or by not displaying a wall texture where there should be one, resulting in an invisible wall).
Computer glitches or the use of computer game cheats can result in both visible and invisible walls becoming penetrable.

It was first widely defined for the American people by Bennett Cerf on the June 20, 1965 episode of What's My Line as "a kink... when anything goes wrong down there [Cape Kennedy], they say there's been a slight glitch."

In some cases, such as a well-timed synchronous circuit, this could be a harmless and well-tolerated effect that occurs normally in a design.

Flip-flop (electronics)

Some electronic components, such as flip-flops, are triggered by a pulse that must not be shorter than a specified minimum duration in order to function correctly; a pulse shorter than the specified minimum may be called a glitch.
