Hi, I met a bug.
I installed plasma-workspace-5.9.3-2.fc25.x86_64 from the copr, and in Xorg.
But I found in sometime, cpu load will be 100%, I often found one cpu is 100%.
PS: just before, I found wireshark is not-responding and one cpu is 100%, so I kill wireshark, All cpu is immediately 100%.

Check to see if you have any zombies. You can do this easily using "top" from the command line.
If so, you can identify the zombies using:
ps axo stat,ppid,pid,comm | grep -w defunct
ps axo stat,ppid,pid,comm | grep -w defunct
You will then get an output similar to this:
Z 2501 18728 xdg-user-dir <defunct>
The number following the Z is the parent process.
Then do:
ps -e | grep nnnn (in this case 2501)
The parent process will be either plasmashell or krunner
Then, restart either plasmashell or krunner by using krunner (alt-F2):
killall plasmashell; plasmashell
or
killall krunner; krunner
That should eliminate the zombie processes and put the cpu utilization back to normal.
