I uploaded a screenshot of Firefox to: http://img406.imageshack.us/img406/9159/31827167.png It happens a lot when scrolling in FF on pages with images, pageup or pagedown don't exhibit it. Text gets corrupted as well, but in a less predictable way. It must be something that FF does that triggers it easily, I haven't managed to get it with other programs yet, though I do see some corruption in the window decoration too sometimes (which is Fluxbox). Scrolling horizontally doesn't show the same behaviour. The corruptions seems to be happening on the right side of a surface/window. Forcing a refresh makes it go away again (e.g. switching to another window or opening another window on top of it. Moving a window doesn't though). I get it with and without xcompmgr running. Okay, interesting titbit: For text corruption, the stripes are one pixel high for the default font size, no corruption for smaller sizes than the default, two pixel lines for 1 ctrl+ bigger than the default, 3 pixels for +2 etc. With bigger sizes (>=5) I get less corruption to the left of the text, but more in the text itself. The distance between the lines continues to increase, but the stripes thickness goes back to 1 pixel. Perhaps an off-by-one error somewhere? > I've created two quick patches to check a few theories, please test them > (both patches independently and both together). Patches attached. Tried with both applied, doesn't change anything.
