When backspacing, the pixels from the character under the cursor not only gets moved to one character cell to the left (as it should), but the leftmost pixel column of the char also leaks to the rightmost pixel column previous glyph. LKML being a text/plain medium, I have taken pictures of the screen for better understanding on how to reproduce, and have placed them at http://inai.de/keyb/ . The font file is also provided there. The kernel I run is 3.4.11 on x86_64. There is no known good version to me (IOW, it is not a regression), as I just started using a 9x16 font on fbcon.
