I'm not sure what I'm supposed to be looking at in that video?

[titiba581]

unfortunatly you can't see it on any videos I took. But it append when ther is things that move to quickly like greens belts or train light flikering.

Hello,
I have noticed this being an issue too, and hopefully i can provide more of a understanding of the issue, im on a Asus ROG Swift Pg279qe at 144hz 1440p, i can notice the effect is like a screen burn that starts after about 5 minutes of non movement, and only after you start to move you notice it slightly, the more time you spend standing still the more the effect can be seen. i have only noticed this issue with the new Turbo Belts so far. a static like image of the belt gets burned into the screen for about as long as you leave the belt onscreen for, in my case it disappeared after about 10 minutes after i think it was AFK for about 15 mins, but the belts burned image stuck around on the monitor even when outside of the game and a computer restart. i think the animation may be the issue but I'm not sure why its only the new belts doing this. its hard to capture a picture, but if it happens again ill do my best.

I ran into this today as well on my Apple Studio Display, Windows 11, Steam edition. I got a distinct turbo-belt arrow pattern left on the screen for ~10 until I ran https://www.youtube.com/watch?v=39HUG7Q ... nBurnFixer for another ~10 minutes.

I found this article https://forums.blurbusters.com/viewtopic.php?t=7539. I don't know much about this topic but "Anything that does exactly a half-Hz or quarter-Hz flicker with no dropped frames for a sustained period" seems interesting, could it be that turbo belt specifically hits this frequency?

I don't know if the issue is 100% guarantee to go away, but sure is super scary until it does given how it persist restarts and display-depower.

If any devs are reading this I'd experiment with tweaking the belt animation speed to see if that solves this issue .

I agree, I am experiencing this as well, 2.0.32. I'm on a 1440p144hz IPS monitor, Gigabyte G27Q. It happens no matter my refresh rate.

Burnin is otherwise known as image retention, for clarity. It's definitely something related to the turbo belt animation rate. With the game paused in editor mode, I experience no effects. If I run the game at 2x speed, I experience no effects.

However, If I leave the game idle, closely looking at a turbo belt animating, I get some image retention around the edges of the turbo belt. I managed to capture it with my phone, with good contrast. To my eyes, also, it appears to flicker. YouTube Link. Best viewed at as high of resolution as possible.

You can see a shadow of the belts on the black paint canvas, as well as when I tab back into the game. I haven't experienced this at any other time with this monitor.

I've just had this happen too; 1080p 75hz VA monitor with a RX6800XT. Lalaith's video reflects what I'm seeing.

[Rseding91]

Maybe one or more of the other developers disagree, but to me, this is a fault of the monitors - not Factorio's animations - and not something we will be changing.

I also have had this issue with an ASUS 1080p 144hz IPS monitor.

I understand saying you won't fix this due to the likely small number of people affected, plus the difficulty in testing and fixing a hardware-specific issue. Especially since as far as I understand, image retention is purely temporary. But given that several people have only seen this issue with turbo belts in Factorio and not any other game, with a variety of monitors, it seems a little unfair to entirely blame the monitors and write it off for that reason.

The job of a PC monitor is to display the images software on the computer requests to be shown. If a set of monitors can't properly show a given set of images then the monitor is defective.
