Welcome and thank you for posting here in the Roku Community, @Tmankiller15!
Thanks for raising your concern with us. No worries. We'd be glad to assist.
May we first know what specific TV you are having this issue with and what specific Roku streaming device you have plugged into the HDMI port? May we also know how long this TV has been used? In addition, does the glitchy and slow performance happen to a specific channel? If so, please specify.
The best course of action will be suggested once we better understand the situation. We'll be anticipating your response!
Best regards,
Carly
