Observed Results

The worldmap cursor position is not scaled properly with HDPI displays for macOS (Windows not tested, scaled resolution not tested) using auto x auto resolution from the vanilla launcher (this is not launched full screen).

This causes waypoints created via the worldmap to not end up where the user was pointing when they created it.

It also causes zoom to not zoom in over the cursor.

It generally makes the world map pretty hard to use (zoom being pretty important for navigating in, out, and around in conjunction with panning/translation movements).

Note, interactivity with buttons is scaled properly.

added through keyboard shortcut

added through right-click worldmap+New Waypoint with cursor over waypoint pointed out

I would be concerned that this probably affects all HDPI, but I have yet to be able to test this on Windows yet.
