That is a bit strange... I am using the latest build 0309 and it all seems to be working fine for me atm... I havent had one force close, etc and I have been updating since the last part of February the day I got my device and instantly rooted and ROMed it to CM10.1 I am also using a OC'ed kernel with no problems... I constantly run different stuff on it.. I do lack playing games and media on it though... I did try playing some music on it once through my stereo and it cut in and out a few times but I thought maybe that was because I may be oversetting the DSP Manager tweaks... but who knows.. I am mainly using this tablet as a nice little netbook occasionally using some other apps as well... I am using my mom's iPad bluetooth keyboard to type this... she wasnt using it and said I could have it so when we visited earlier today I snagged it from her... and it is working great... very smooth
I can't complain about these nightlies or kernels because they seem to be doing exactly what I am requesting of them... I haven't really noticed any lag as well or irregular battery drainage and I think I have been overclocking at around 1400 mHz max and 800 mHz min settings since this last CM build release... so I would suggest maybe a clean wipe and install and see where that takes you.. but personally, I have only did the initial wipe and install when I first rooted and installed CM19 goodluck with your endeavors for those who are having issues.
