- Steps to reproduce the issue you are seeing: Display any video source on any HDMI port with game mode enabled. It does not matter if it's an xbox or dvd player or mini game system or computer. Anything plugged into HDMI exhibits this issue.
I have been doing my own testing and I believe it has something to do with your frame buffer (I'm assuming you're using a frame buffer for video processing when not in game mode - correct me if I'm wrong).
When you turn on game mode, it should be disabling the frame buffer and all video processing. But it's acting like the frame buffer is somehow turning itself back on for 0.5 seconds every 10 seconds. This results in a short "jitter" where the screen appears to jump back in time (buffered video) and then jump forward to present non-buffered video. I could be wildly wrong about the cause, but the symptom is exactly as described. Whatever it causing it, the jitter makes the image jitter or jump twice every 10 seconds, which is not only distracting but, in many cases, makes it impossible to play games.
To be clear - I have tested ALL my video sources on another brand of TV and there is no jitter. This is only happening on my Roku device, and only since 12.0.0.
Further, turning off game mode (reenabling the frame buffer?) seems to temporarily resolve the issue, which I guess would make sense since there's no "jump" when the buffer flips on and off. This is NOT a solution, however, because THEN YOU'RE NOT IN GAME MODE and the buffer creates noticeable input lag when playing games. And then if you turn game mode back off, the issue returns.
To make things even more interesting, I have noticed that -sometimes- turning off game mode and then turning it back on -seems- to temporarily keep the issue from happening. But this is temporary and I believe it may not actually be turning on game mode / disabling the buffer when this happens.
But this is all just my own testing. The facts remain: This is an issue that began exactly with 12.0.0 and is very much software generated. I wouldn't be surprised if every device out there is experiencing this and people just aren't engaging in activities sensitive enough to notice (such as fast-twitch gaming). Or perhaps 12.0.0 is especially taxing on certain cheaper/older devices (I don't believe it's a processing-power issue because it's happens on an exact cycle of 10 seconds); but still, if it is simply that 12.0 is too demanding, PLEASE let us downgrade. I don't need new features. I don't want skins or live ads. All I need it the gaming TV I bought to work.
