I'm using SmartTube Next on a Nexus Player. Sometimes when I open it, it works flawlessly. Other times, it absolutely cannot play videos properly. I get massive drops in frame rate. Watching things like sports highlights becomes impossible. Audio is never an issue. Videos load fine, but the frame rate is abysmal. It seems to happen at random too. Some days it works perfectly fine.

I know my wifi isn't the problem because the official YouTube app never has these issues, and I have very good internet. Any tips on how to fix this? Is it just because I'm using an OG Nexus Player or is there a setting change I can make? Any help is appreciated.
