Summary	08349: turfmast: Related to issue 03972, horizontal shaking lines for the Japan course
Description	Some courses don't have this bug at all, but the Japan one does at any point where you adjust your position/angle. This was talked about in 03972 but it's a very old thread and incomplete. I was able to reproduce the issue every time on Japan course 1 in MAME 244, 231, 203 and 174, all official binary MAME releases for Windows. Doesn't seem to be a regression. The lines will wobble more the more you rotate and keep on wobbling as you stand still like in the video below. The following clips are all of the Japan course 1. Video of the glitch: https://i.imgur.com/J1u5Kyo.mp4 Video clip of how it should behave: https://i.imgur.com/wzsPGIS.mp4 Since my CRT capture sucks I found a direct video capture of real hardware at 3:28 this same movement results in shaking lines in MAME, another angle adjustment at 3:48. (removed link to unavailable video) Neo Geo CD version behaves the same way in MAME.
Steps To Reproduce	Select the Japan course and rotate your character 1 step, a single line starts wobbling, rotate another step and more horizontal lines start going wobbly and the more you rotate the more horizontal lines will wobble, and none of it stops as you're standing still.
