Comment 122 for bug 1098334

Just received new debs of the intel driver (2.21.11 + snapshot taken 13-07-08, git dbb585), libdrm (2.4.46 + snapshot 13-07-08, git f8f1f6). Furthermore, I have also received a new 3.8 kernel from ubuntu a few days ago that may contain some drm changes (but I am not certain of what goes in since it is a distribution kernel, not mainline).

Now, I think that I am experiencing a lot of this too (or maybe it is something else, please advice). Particularly when writing emails with thunderbird, all of a sudden I notice that some character is corrupted. This seems to happen even without explicitly scrolling, but just typing. Very strange.
