These characters are: AKkRrTVWwXxYyZ. This problem only occurs when I have my second monitor enabled. The cursor is a blinking black box such that when the cursor is on top of text, the text is printed in inverse (off-white). What happens after typing one of AKkRrTVWwXxYyZ is that the black box is moved to the next position, but the character I just typed blinks as though the cursor were still on top of it. The next letter I type then appears twice: both in the correct position, and also overprinted on top of the problem character to the left. Also, the problem character is then re-printed one position to the left of where I typed it, overprinting on the character before it. Further typing appears normally, as long as the characters are not any of AKkRrTVWwXxYyZ. For example, if I type "text" weird behavior starts after I type the lowercase "x". What I see before I type the second "t" is "tex" with the blinking black box to the right of x, but x is also blinking (alternating black and off-white). After typing the second "t", what I see is "t#*t" where # is "x" printed on top of "e" and * is "t" printed on top of "x". If I move the cursor away and type C-l the text is redrawn correctly, but if I move the cursor back over the problematic characters, the overprinting reoccurs. This is on my laptop running Ubuntu Maverick. The problem occurs when I have my external monitor enabled (regardless of which monitor the emacs window is on). When the external monitor is disabled, the problem does not occur.
