Let's say that I click on the screenshot app that comes bundled with Ubuntu 11.10, and then select "select area to grab" followed by drawing the desired area, the resulting screenshot that is captured is, too often, coated with an Ubuntu-coloured glaze.
For example, if I screencap this Ask Ubuntu website, the white areas (all area, in fact) will come out with an orange hue. I'll cancel and repeat the process until the result is correct.
Does my description help? If so, then any idea why it happens and how to fix it?
