Tips and Tricks

Warning! In some versions of the KDE Plasma 5 Workspace (5.7.x for example) after the installation and activating Bezier Clock you can see a black screen. It is due to these bugs here: bug #1 and bug #2. Reset to default settings using the "Reset To Default" button and click "Apply" for fix it. - Not relevant for the v1.1

To reduce the load on the CPU cores, lower the value of the option "FPS Limit" to acceptable values. To ensure a smooth animation at low FPS, you can adjust the option "Animation Duration", with lowering its value. For example, a 25 value of "FPS Limit" and 30 of "Animation Duration" gives a good result.

Run Bezier Clock, experiment with the options and enjoy!
