I'm currently seeing this same issue on my TCL Roku TV (a few horizontal lines of pixels near the top of the screen seem to be updating a frame later than the rest of the display) but not with streaming channels; I'm seeing it with HDMI devices (particularly game consoles) - I suspect but haven't 100% confirmed that it only happens with 720p signals.
This only occurs with Game Mode on, but of course if I'm playing games I need that setting. I'm on the latest software update. Any idea what's causing this and if I can fix it?
Yep. That issue with Game Mode for 720p and 480p has been present on my TCL Roku TV's (2018 6 Series) since forever. No updates have ever fixed it. I've seen others mention it over the years, so I'm pretty sure it's a universal issue.
This thread gave me some hope that it might finally be addressed, but I'm still unsure as to whether or not that will actually happen. It's a huge flaw for anyone who plays retro games.
Okay, so I've actually found a very, very silly workaround for this. I don't know why this helps but it's been consistent for me every time I've tried it.
What I do is, if I'm seeing the Game Mode tearing issue, I start casting to the TV from my smartphone (with my Samsung Galaxy phone, this is called "Smart View"). Once the cast from my phone starts, I stop the cast right away, which takes me back to the TV's home menu. Then, when I open the game console "channel" again... the issue is gone. Until the TV turns off, anyway.
So yeah, still unacceptable behavior from the TV software, but at least there's a workaround. Maybe this helps diagnose the bug?
Ours was working fine a few hours ago and now is ALL vertical bars on playback. Menus are fine, it’s in multiple apps(Disney+, PBS kids, Hulu). We’ve power cycled and reset to factory audio/video but not full reset yet. any hope it’ll work after being unplugged for several hours?
This morning when my wife went to watch some T.V. we now have an intermittent horizontal white line at the very bottom of the screen that lasts for a couple seconds the disappears for a few seconds then repeats. When this happens the screen gets slightly blurry. This happens on every screen (home screen, streaming channel, DVD, etc.) but has never happened before today.
I have tried turning the T.V. off for a while, turning it off and unplugging it, performing a factory reset, all to no avail.
Needless to say this is very frustrating. Hopefully someone can help.
Has there been any acknowledgment at all yet from Roku about the artifacting at the top of the screen when using Game Mode for 480p or 720p content? While I'm not hopeful that it'll ever be fixed at this point, I would feel much better to at least know that was a known issue on their end.

Oh, I wanted to pop in to say that this workaround didn't work for me on my TCL 6-series Roku TV.
Toggling Game Mode off and then back on used to fix the issue pre-Roku OS 9.3 I believe, but ever since then there's just no fix for this. It's so ridiculous.
