for what it is worth i see things that are unexplained or undesirable with custom roms. sounds great. if you like to fiddle. wonderful. if you just want it to work go stock. best chance.
unless someone here is running that same rom we gonna be guessing at your question. in this case you may then turn to xda forum and ask others using your rom.
it really does matter thanks for mentioning that. i have read a pretty good number of posts with folks having issues that in the end they found it was the special rom that was the problem.
that would be a small quirky thing that would happen with a special rom....driving you crazy.
