When, I use some specific themes like the Vimix theme, xfce4 and xorg combined are using more than 90% of CPU!
If I go to Panel Preferences -> Appearance -> and change Background Style from 'None' (use system style), to 'something else' the the CPU usage reduces to normal.
I have modded the vimix theme it can be found: Here
This theme also wastes > 90% of CPU, what is causing it? How can I fix this bug?
