Default [Q] Background failing?

Hey guys!

Last night I installed venom 5.8 onto my HTC One. Its working greatso far but one thing is starting to bother me, sometimes when I go into the "Venom Tweak" application the home screen background fails and goes completely black. If I go into the settings and change it, it continues to stay black until I restart the phone. Any idea how I can go around fixing it.

Thanks in advance!!
