+# command line option to be used, in order to enable the usage of the
+# dual-kawase blur method.
+
+# NOTE 2: With the picom from standard repositories, currently using experimental
+# backends will disable the support for rounded corners. If you want to use both
+# the dual-kawase blur method and rounded corners, you will need to use a fork.
+# However it is not mandantory. If you will use the standard version, you will just
+# see a warning in picom's logs each time it's started, you can disable rounded
+# corners completely to prevent this. If you do want to use a fork, I recommend this:
+# <https://github.com/jonaburg/picom> (picom-jonaburg-git on AUR).
+
+# NOTE 3: The shadows are currently disabled, the reason for this are the issues
