What's the problem? Describe what went wrong.

Badminton (Air Rally in US copies, I think) renders incorrectly in Remix 3. A line is visible in the sky, regardless of internal resolution or manual texture sampling. It renders correctly in other cases.

What steps will reproduce the problem?

If needed, download a 100% save from here.

Simply start Remix 3, and wait until Badminton is being played (~30 seconds). Look at the sky; a line will be visible.

Is the issue present in the latest development version?

Yes, 5.0-16101

Is the issue present in the latest stable version?

Yes, 5.0

If your issue is a graphical issue, please attach screenshots and record a three frame fifolog of the issue if possible.

I've attached fifologs for the affected version of Badminton, as well as the main version and its introduction (which are not affected).

What are your PC specifications?

• CPU: Intel(R) Core(TM) i7-10750H CPU @ 2.60GHz, 2592 Mhz, 6 Core(s), 12 Logical Processor(s)
• GPU: NVIDIA GeForce GTX 1650 Ti
• OS: Windows 10 Home 10.0.19042.1526

Is there anything else that can help developers narrow down the issue?

This vaguely reminds me of the line down the middle of the screen in NHL Slapshot, as I remember determining a similar cause for that (however, I can't find the bug report for it).

The affected bit of the sky texture comes from a single large texture that serves multiple purposes; the sky texture is from (856, 8) to (879, 247) with a transparent black border around it. When drawing the sky, the texture coordinates range from (.843751024=864, .00781251024=8) to (.85156251024=872, .24218751024=248); this goes slightly out of bounds on the vertical axis (although the problematic bit seems to be the y=8 part, not y=248?). This texture is actually used in two instances, with the second one being flipped vertically; the fifo player seems to incidate that there is a dark line on both, but the second dark line is overwritten by the checkerboard floor.
