Red squiggly lines are rendered in inverted colors

The problem: Red squiggly lines are rendered in inverted colors, making the above text hard to read.
I expected to see: a red squiggly line, under black text on a white background.
I saw: a blue squiggly line, on a black background and partially white letter (a block where all colors are inverted)

The issue is not client specific - I encounter it on all machines I connect to.

As you can see in the attached screenshot the red on white squiggly lines show as blue on black (inverted). When connecting to the same machine using the windows RDP client the line is rendered as expected(red on white).

I encountered the bug in this version:

This problem is also persistent in the very latest version of the remmina-plugin-rdp package (from the remmina-next repo)
