Verzephobia

The fear of graphical errors, distortion, visual glitches, especially in video games.

Often, a sense of fear is especially triggered when a humanoid or 'alive' NPC or player glitches through walls, the floor or changes shape, size, colors or details.

The name comes from the German word 'Verzerrung', meaning distortion.

Although there seems to be little to no problems with intended glitches, for example in the game DDLC (Doki Doki Literature Club), once known they are intended.
