i can not change the compositing mode in plasma 5 because is not showed, i had egl mode in a laptop with amd catalyst and i had to change the mode in kwin config file to glx


Reproducible: Always

Steps to Reproduce:
1.launch kcm

2.go to screen and compositing


Actual Results:  
in the part where before were the compositing modes there is nothing to choose 

Expected Results:  
the possibility to choose betwin egl and glx modes

if you go to .config and search kwin config file you can change the compositing mode again, but before you can from the gui of kcm..
