Xfwm Effects is a hack of the Xfce compositing window manager that adds depth and color harmony to the appearance of the desktop, without adding distraction. It does so by creating an image of the desktop when necessary, then uses the Imlib2 library to blur the image, then uses Xlib compositing commands to composite the image onto desktop windows, panels, menus, and popovers. The effect is reminiscent of Apple's 'vibrancy' effect. Using this method sidesteps the computationally expensive need to continually generate gaussian blur.
Also included is the Xfwm Effects app (xfwm-effects) that allows the user to turn the effect on and off, to adjust the amount of blur, and to adjust the amount of color composited (for light themes). Note that to see the effects, 'Compositor > Enable Display Compositing' must be selected (i.e., active) in the Window Manager Tweaks app (the compositor is used to draw the effect). Adjusting the sliders on the Compositor tab of the Window Manager Tweaks app toward 'Transparent' will make the effect more pronounced.
Xfwm4 version 4.16.1 (64 bit only), or Xubuntu 21.04 release version of Xfwm4. Xfwm4 is the Xfce4 desktop environment's window manager. 'xfce4-about' in a terminal window to see the version you have.
The installer script is written for Xubuntu 21.04 ; other distros will need some massaging to get xfwm-effects to work.
