There is an issue of uneven scanlines when using multiple lines #128

This issue has been present in previous versions, not just in the latest version.

In the case of 2x lines, the scanning lines are basically uniform.
It may be due to the low magnification and blurry image.

In the case of 4x and 5x lines, there is a noticeable issue of uneven scanning lines.
The interlaced black lines themselves are uniform, but the bright lines are uneven.
The scanning line image features shown in the following figure:

Image

The previous bright line is 3 vertical pixels, the spaced dark line is 2 vertical pixels, and the next bright line is 2 vertical pixels.
Arrange the full screen scan lines in this order.

In the 5x case, the bright line becomes 3 pixels and 2.5 pixels (with one pixel half bright).
A dark line is 2 pixels, and the dark line after a bright line becomes 1 pixel.
This resulted in severe unevenness of the dark lines.

In this case, when the depth of the scanning line is increased to over 50%, it is obvious that the scanning line on the screen is uneven.
Can you control the vertical pixel values of all bright and dark lines to be the same?
