What kind of bug is this!?

Posted: 2009-07-11

So, i've been using a sort of messed up install of Ubuntu because i was testing the Jaunty alpha way back when, and never did a clean install once the final version came out. I get some weird bugs every once in a while, but they're minor so i tolerate them (although i will be sure to do a clean install for every new release from now on). I'm never sure if a bug i encounter is an actual bug, or just a side effect of upgrading from an alpha. One of these strange bugs is that, very rarely, when i'm browsing in Midori, although it did happen once in Firefox, a black bar, a few lines of text thick and the width of a web page, will appear. It goes away when i scroll so that the bar is out of view and then scroll back, or if i minimize and restore the window. Anyways, one time, something a little stranger happened...


That's clearly the cutout of a giant star. The black bar was a box covering the entire page except for this huge star. What the hell is that doing there? That screenshot isn't perfect since i clicked something before capturing it which made some blocks go back to normal, but the huge star is still clearly visible. Is this something other webkit-gtk users have experienced and how the hell could that star have gotten there?
