After update to OS X 10.11 I started having these bugs:
-
Finder sidebar text flashing
Video -
Very high CPU load:
I have Macbook Pro Retina 13" Mid 2014
I reset NVRAM.
I deleted com.apple.finder.plist, it didn't help.
Also I did this: link, no longer flashes.

For your high CPU load, let's dig into the system.
vm_stat 60
- collect 10 minutes of data and look at the columns belowiostat 60
for about 10 minutes - Control+C to quit both the "stat" commands.To load my Mac, I downloaded 10 apps from the Mac App store - some large ones like iMovie and Garage Band and some small ones like iWork and such.
You can see here the the load averages are CPU intensive, but the IO went down as my software updates all stopped writing to disk.
Similarly, not all the vm_stat numbers are meaningful. The most important is faults and that shows how busy the memory system is. Next is free, if it's too low (less than 100) for other than one interval, then you are constantly paging in and out pieces of data. That will show in the last 4 columns: ** pageins pageout swappins swapouts** The few out operations in my sample show this re-balance, but a constant flow of them indicates you can tune your system or software for better speed.
