Version: (using KDE KDE 3.1.2) Installed from: Compiled From Sources Currently it's impossible to know if a certain pixel is transparent or simply grey. A visual marker to differentiate between the two is needed. Possibilities could be to hatch transparent pixels or to give them a 'weird' user-defineable color/pattern instead of the generic grey.
CVS commit by page: Add the ability to render the background as a checkerboard pattern or a solid colour, making it easier to distinguish pixels with transparency.
