Default having weird issues, if someone can point me in the right direction

I've tried several custom roms and with all of them my video players have problems(mx player.. etc) the phone usually crashes, also no matter what battery icon I use when the phone charges past 90% the color of the percentage turns cyan, I've tried changing the settings no luck, currently I'm on dirty unicorns nightlies, no xposed modules, always clean install, anyone got any suggestions?
