However there are some rendering glitches that happen rarely. The most common of these is text rendering glitch in Firefox. What happens is that every now and then a letter is drawn incorrectly. It may be drawn as (semi)random pixels or a zoomed part of some other piece of text. On redraw (triggered by e.g. pgup + pgdown) the text is drawn correctly. Attached is an image showing the corruption. It is taken with a camera, because trying to do a screengrab forces a redraw which clears the error.
