Using xfce-shapes as desktop background produces a white line at the rightmost side

Issue Description

When using the xfce-shapes background (xfce-shapes.svg file), there is a 1 pixel wide white vertical line at the rightmost side of the screen. This happens only after I upgraded my system today. This is a cropped screenshot of the desktop, around the bottom right corner:

It seems that the problem is within the xfce-shapes.svg file. When I opened it in Inkscape, there is actually a white line at the very rightmost side. Here is a cropped screenshot of the file opened in Inkscape, zoomed in, at the same location:

When I imported it into GIMP, there is instead a transparent line at the right side. Here is a screenshot of the same location, zoomed in, after importing into GIMP:

I'm using a distro package (Arch Linux), but I downloaded the file from this repository, and they match. The weird thing is, the file was last modified inside this repository 2 years ago, but before upgrading my system today, I have never seen such a vertical line.

Steps to Reproduce Issue

1. Upgrade my system.
2. Reboot, then log in as usual.
3. Issue appears.

Expected Behavior

I would expect that there is no such vertical line.
