I'm afraid switching to UXA didn't solve the problem.

OS: Ubuntu 13.10
Kernel: Linux foobar 3.11.0-13-generic #20-Ubuntu SMP Wed Oct 23 17:26:33 UTC
2013 i686 i686 i686 GNU/Linux

lspci | grep 'VGA\|Display'
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series Chipset
Integrated Graphics Controller (rev 07)
00:02.1 Display controller: Intel Corporation Mobile 4 Series Chipset
Integrated Graphics Controller (rev 07)

I have random single char corruption with all three - EXA, UXA and SNA -
acceleration methods. I didn't see any notable difference. 

I will test it with older kernels soon.
