Neither the settings on their own, nor the combination of them fixed it.

Please record a fifolog (when on an affected screen, select tools -> fifoplayer, then record, then save) and attach it here (compress it with 7-zip if needed).

Thanks. I tested it out with the hardware fifoplayer, and some of the lines were still visible there, but to a lesser extent than those in Dolphin. More of them are visible when I use the hardware fifoplayer to take a high-resolution screenshot (note that doing that is very hacky, and the texture scaling issues are an artefact of that process which would not normally be visible). In particular note the vertical line next to the "N", which comes from the nearby "T". (You can use the object range functionality in the fifoplayer to see in what order the game renders things; part of the T to that N is a single object.)

The game has linear texture interpolation enabled, and texture wrapping enabled, so drawing the whole texture means that the edges are an average of both sides. So in that sense, this is correct behavior on Dolphin's part. But, at least with manual texture sampling, only the lines that appear on real hardware should be visible. #12857 is a similar issue.
