[Miscellaneous Android Development] blakegriplingph:
Seems like we need to adapt what I saw on this repo as the MediatekHacks.cpp I threw in to fix the missing symbols issue may have accounted for why SurfaceFlinger isn't cooperating.

[MENTION=3064479]pix106[/MENTION] - Did you by any chance use the repo I mentioned above when you built your ROM? I've used the vanilla CM android_frameworks_native repo for one and that may have accounted for why my ROM is spazzing out. Also, I saw a commit by thp1997 (along with a patch of similar intent by [MENTION=5317117]Kirito96[/MENTION]) which appears to be a patch/shim set for the MT6572 that seems to tackle the same issue as what I've been experiencing with the Epic. The crash log...

...appears to allude to the ones mentioned in the patch files. Maybe this is the cure we needed, short of using a different HWC which I more or less doubt to be necessary.
