The :guilabel:`Shadow` tab manages how compton draws shadows. To toggle enable client side shadows press the Enable client side shadows checkbox. The checkbox for Aviod drawing shadows on dock/panel windows will stop drawing shadows on the panel. The :guilabel:`Color of shadow` lets you change the color of shadows from windows. The field for :guilabel:`The blur radius for shadows` changes how big to blur the shadows. :guilabel:`The left offset for shadows` is how far to move the shadows to the left with a larger number makes the shadow appear farther to the right. :guilabel:`The top offset for shadows` the larger the number farther down the shadow appears below the window. :guilabel:`The translucany for shadows` is how opaque or clear to make the shadows 1 is opqaque shadows and 0 is clear. The :guilabel:`Crop shadows of maximized windows from extended displays` checkbox does not have shadows across multimonitor layouts on other monitors from windows on another.
The :guilabel:`Opacity` tab is for transparency settings. Setting Opacity to 1.00 makes it opaque while 0 makes it entirely clear. Menus, inactive windows, active windows titlebars and borders all can have their opacity changed indepently. The :guilabel:`Blur background of transparent windows` blurs the background of transparent windows. To not change how far a window blurs on window transparency check the :guilabel:`Do not let blur radius adjust based on window opactiy`.
The :guilabel:`Fade` tab manages fading windows opening or closing or opacity changes. There is a checkbox for :guilabel:`fade windows during opactity changes` so if the opacity changes it will smoothly fade. To have a slower time between fade in miliseconds increase the :guilabel:`The time between steps in a fade in miliseconds`. With this settings windows will fade in and out when opened and closed unless you don't them to which you can check the :guilabel:`Avoid fade in out when windows opening/closing`.
To have your settings applied you will need to press the :guilabel:`apply` button. If you want to cancel your changes press the :guilabel:`cancel` button.
from the command line. From LXQt configuration center press the gear button with a c in it to launch Window Effects. Of course for this to have any effect the compton compistor needs to be running so see chapter 3.2.13 for how to autostart applications.
