- Add --glx-fshader-win, which specifies a custom fragment shader for painting windows. compton-default-fshader-win.glsl is the shader with default behavior, and compton-fake-transparency-fshader-win.glsl provides a template of fake transparency. (#183) - Add --force-win-blend to force all windows to be painted with blending. - Add --no-fading-destroyed-argb, as a workaround of bugs in some WMs. (#193)
