edit, missed the status bar thing you said, on the vitria(don't have the valiant) for that their is a weird solution you can take the systemui from the huawei ascend mate and replace the systemui in app, that is a roundabout way to fix it, systemui will crash soon as you copy it but reboot and it should be fine and then you can change transparency and enable center clock and stuff in gravitybox and other xposed apps without having the issues at all.
might work on your valiant too, might not -_-
pics for u on the vitria
huawei themes still work until you install xposed then it does the same thing stock does(toolbox resets with icons)
systemui here(backup yours just in case)
