Public bug reported:
3D rendering landed recently for Southern Islands cards. 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.
