The Intel Express Integrated Graphics Controller (945GM?) uses main memory for graphics. Remember, this is the font table that is getting messed up, and I presume it is either X or gnome-terminal that manages that table and renders the display windows for that. The 945GM does not have a font rendering engine. When I switch virtual windows, X rerenders the window, presumably with the help and saved state of each application. Since I don't see this behavior in Firefox or the other applications, and the disk copy of the font table remains intact (it is there when I restart X), I presume the corrupted table is in RAM and belongs to gnome-terminal or X. However, your suggestion does inspire a clue - since the busted pixels are always stored in a table in RAM, perhaps something is interfering with the RAM refresh for that. I will run memtest86+ with the "bit fade" option - that takes 3 hours, I'll run it tonight. If there is another program I should run that keeps the memory bus too busy to run refreshes - is that possible? - I should try that.
