Black bars appear where text should be

[John Scott]

Sometimes if you go to a website with special text formatting, instead of text, you will see black and gray bars where the text should be. If you select the text with your mouse, it often becomes visiable again, but returns to a bar when you stop selecting. This reminds me of an old Firefox bug involving the address bar I had on the same computer. Perhaps these bugs are related and it's a video card problem or something?
