A visual bug, also known as a graphical user interface (GUI) bug, is a defect in a software application’s appearance or layout. It occurs when the visual elements of the user interface, such as images, text, colours, or formatting, do not display or behave as intended. Visual bugs can include issues like misaligned elements, incorrect colours, overlapping text, or distorted images, which affect the usability, aesthetics, and overall user experience of the software. Identifying and resolving visual bugs is essential for ensuring the quality and professionalism of the software product.
