Yesterday I upgrade my system to newer Fedora 28,after that,I get two troubles:The one is that in my KDE Plasma desktop,display effections didn’t work(For examples,Window alt<ALT+TAB>,Window vibrate) except desktop transparent.The other one is that driver installation overrides libOpenCL.so.1 file,this causes video play didn’t work.The next trouble I resolved by reinstal ocl-icd package.The first one is still here(Not resolved).
This is a KDE plasma Bug,not for nvidia driver.After update kde plasma,all works fine.
