[Q] Cyanogenmod 10.2 : Sudden lags while typing via keyboard topic

I have an E975 and I am right now on Cyanogenmod 10.2 stable with the included cm kernel.

I type fast enough with the onscreen keyboard and even if I type slower, I get sudden lags while typing an sms or a note or entering contact details or web addresses. The lag stays for a good 5-8 seconds and the phone is in a situation of a hic-up. The letters I press on keyboard don't pop after the lag-surge is gone.

Is there any workaround for this? (I am not sure but for samsungs there were lag-free tweaks to work around problems like this)
I am willing to switch roms but preferrably AOSP/AOKP/CM based and not the stock ones.

Please advice

Thanks
