Backend live TV video issues

Can’t seem to find answers searching. Ever since changing to version 17 from 16 my live tv whether through ServerWMC or HDHomerun pvr add-ons my video has been glitchy. What I get is about 3 lines or so on the bottom of the screen going all black for most part. It’s not completely whole thing, it’s like jagged. It is pretty constant, sometimes screen completely fine for few sections then back to messed up. I’ve tried changing hardware acceleration under video tab with no luck. This is running on Fire TV and one both TVs with FireTV boxes.

Help would greatly be appreciated, been living with this for few months now and driving me mad. Thanks.
