Emacs on Ubuntu. Playback issues: text is displayed above other text

I'm new to emacs, just starting to like it - but today, after launching, the next issue made it unusable.

Problem: When I move the cursor forward, some, but not all, characters appear unreadable. The next letter in the line is displayed above the previous character, not replacing it, but displaying simultaneously in the same place. Obviously, I can’t show this because the text editor on this site is working correctly.

A few examples of what I have tried so far, without effect.
1 restart gdm
2-apt-get install rxvt-unicode - check if there was a problem with xterm
3.dpkg-reconfigure emacs
4. Uninstall and reinstall emacs23 completely with the .emacs configuration file.

Converting Ben's comment to an answer to get it from a list of unanswered questions:

The problem seems to be font related. If I do the following, this will work:

  • type-xlsfonts - to the terminal and get a list of available fonts.
  • select one of the monospatial fonts (for example, r14) and check by doing: emacs -fn r14 myfileName

To do this by default, go to the options menu in emacs, then -> Customise Emacs -> Specific Face -> and enter: " default " and click " set for future sessions ".

Today I faced the same problem. Setting the last snapshot instead of a stable branch allows it:

 sudo add-apt-repository ppa:cassou/emacs sudo apt-get update sudo apt-get install emacs-snapshot
