KWin has nowhere a realistic shadow model - there's no lighting concept lik= e in eg. a game (and you would probably not like that either) The shadows are just some translucent parts of the window (decoration) Leaving your trivial case aside, this cannot be resolved in a reasonable wa= y, eg. depending on the implied light model, the shadows between two windows w= ould either have to overlay (strengthen each other) or there must not be any sha= dow at all (because of the central light) I won't say "come up with a patch", but you'd have to provide a complete and self-consistent concept for shadows that you'd prefer (and I postulate that= you will not prefer a realistic light model, also because very few light setups would generate the type of present shadows. Try to cast such a soft fading shadow at home ;-) Ftr: ----- a stack of windows would indeed reduce the amount of ambient light (reflect= ions from the window backsides), so to a certain degree (a black window hardly reflects light) the present behavior is actually justifiable. --=20 You are receiving this mail because: You are watching all bug changes.=
