Hi,

I get a horizontal line of screen tearing happen in a localized part of the screen, it moves to a different location when the game is restarted, with or without v-sync enabled. Also was apparent in 0.17.46. I attach a picture using my phone to show the tearing, screenshoting or video recording from PC does not show the issue.

Thanks

Reading from a post in factorio sub-reddit, going into nivida settings panel and turning v-sync off and on again fixes the issue, dont know what has changed in 17.46 or 17.47 because 17.45 ran fine without issue prior to doing this.

Thanks for letting us know.

In 0.17.47, I changed default presentation model from old Blit to new Flip, which should be more efficient, because it allows DWM (desktop window manager) to compose the game onto a desktop without making extra copy of our framebuffer and in fullscreen mode DWM can circumvented entirely, and the framebuffer is presented to screen directly.
I am not sure why v-sync needed to be toggled on and off in nVidia Contol Panel, but I am glad it solved the tearing issue for you.
