iOS Nightly Video/Display Problem

I have a problem with the nightly builds where, after choosing a core and rom, gameplay does not display video. Audio works, as do overlays. Running on iPhone 6 iOS 8.1.1 (Taig Jailbroken). Permissions are set to 775 on both the RetroArch file and .app folder. I haven’t seen the issue brought up yet and I’ve been having this problem since the 3-5-15 build.
