Improper scaling (16:10 screen with @2x scaling high dpi)

[p0358]

But seems there are issues at various sizes:

At a glance it seems the CSS might be mixing up various units, could be partially why. Zooming out to ~60% or even 50% fixes most of the issues to the point of being viewable, but it also makes some other elements too small, but this hints at this being a problem with high dpi I guess.
