error in running Matlab after updating El Capiton 10.11.4

hi,

I have some problems in running the Matlab and COMSOL after updated the El Capiton 10.11.4.

my MacBook Pro (Retina, 13-inch, Mid 2014)

2.6 GHz Intel Core i5

8 GB 1600 MHz DDR3

after this upgrade, my Matlab is very slow, and the CPU use always upto 300%, even in idle.

Is this caused by OS?

Here are some details:

when I run my COMSOL livelink with Matlab(R2015b), there shows the following when the Matlab initialzing which never shown before , :

and the XQuartz shows:

I see someone posted the 'IMKClient Stall detected,' is due to the updated OS.
