Well I adjusted the page settings so they're on the same page now. But re-making the bugged glissandos is actually easy -- look for violas in measures 102 to 103. The notes are not supposed to be there -- they're just a demonstration of the bug.

The main thing to make sure you have in the setup is hidden staves so the measures on one page do not line up with the measures on the next page. The glissando lines are then drawn so they will point at where the notes are on the other page. So if you have measure 1 with a C4 and measure 2 with a E4, but there are more staves visible on the page with measure 2 the glissando will actually point down on page one, even though the next note is higher. That is what is being shown in the original picture.

There is not hidden staves. In fact, there is a lot, in upper staves, of elements (staff text, slurs) which increase the distance between staves and so impact the position of the glissando. For example, delete all slurs and "arco", and other, in the previous staff, and it's solved or grantly improved. And so on with other.
I don't know if this can be considered as a bug. Not sure. As said by the user, change the layout to avoid the glissando to be in an uncomfortable position, "I adjusted the page settings so they're on the same page now", and the problem is gone.

Hidden staves or staves spread out due to automatic placement have the same effect. The important thing is that the staves in the two measures not be at the same point on the page. I was giving a scenario I had noticed before.

It should be a bug because it makes the score look wrong. Down-pitch glissando shouldn't be going graphically upward by any means.
