an inconsequential but strange bug
I have tried three distributions for a substantial length of time--Mandrake, Xandros (open circulation edition) and Knoppix (some build from mid-2005)--and in all three, I have run into a phenomenon which does not affect performance but obviously should not be there. The title bar (and very occasionally, the desktop and random applications) fill with various forms of gibberish. The gibberish usually consists of white-to-gray vertical bars or squares (in Mandrake and Xandros), but can sometimes consist of random letters (in Xandros). For some reason, it was much worse in Xandros than in the other two; the gibberish was bad enough to block what was on the screen at times, and I blamed Xandros (incorrectly, as I later figured out) and tried another distribution. I was most puzzled to notice, recently, that Knoppix has it too; that is very peculiar, because being a CD, it can't be corrupted by anything, can it?
Since this bug has appeared in three different distributions, I suppose someone else out there must have seen it too; but I can try to get a screenshot from Knoppix (that's the only thing I'm using right now) if needed.
