(Q) How do you get no transparency on COS12.1 Lockscreen?

Hello everyone i am on the latest COS12.1 Stock ROM and i am rooted with twrp installed. I was wondering if anyone knew how to get the lockscreen wallpaper to not be transparent. If you still don't know what i mean is that i want the lockscreen wallpaper to be as bright as the home screen wallpaper.

Thx in advance:)
