Display scale 150% is missing

[cargodog]

Describe the bug
The 150% display scaling option is actually 175%.

To Reproduce

1. Open settings > Displays
2. Change scale between 150% & 175% and you will see no difference

Expected behavior
150% scale should appear smaller.

Screenshots
I've attached three screenshots (125.png, 150.png, 175.png) showing my screen at each of the scaling options (125%, 150%, 175% respectively). Notice the "Scale" setting in each shot, and then look at the text size in the open windows. See that 150% is too large and identical to 175%. I can't comment on whether the 125% or 175% settings are correct, just that the 150% is wrong.

125% (maybe correct?):

150% (definitely too large):

175% (maybe correct?):

Desktop (please complete the following information):

• OS: Arch
• Display Resolution: 2880x1800 (Nitropad v54 laptop)

Additional context
This changed as of the latest cosmic release in the Arch repositories. I'm only so confident that 150% is wrong, because I daily drive at 150% and now everything is painfully oversized 😆

Unfortunately, my 150% and 175% scaling are different. However, 150% has some weird scaling issues with some apps which does not happen with 125%
