Applications work too slow on intel gpu

I'm using Arch on Asus Zenbook UX32VD. It has Intel Core i5 3317U and NVIDIA GeForce GT 620M.
I realised that when I run some apps working with text (IDEs or browser) from intel gpu text animations (selecting, cutting/pasting or even typing) have delay up to couple of seconds, also cursor blinking animation is like 5 times longer. So when I run same apps from nvidia using bumblebee everything works fine.
What can cause behaviour like that and is there way to fix it?

Re: Applications work too slow on intel gpu

What driver are you using on Intel?  It sounds like you may be using the frame buffer driver.
Check you Xorg logs.

Re: Applications work too slow on intel gpu

I was wrong.  That is using the i915 driver.   Sorry for the noise.
What is the output of glxinfo ?
