Hi Frederick, there is some special case processing happening for the line case to make it show as a dot and it's just more difficult to do it efficiently for the plane case.

One thing you can experiment with though is reducing the transparency for the edit frame grips if you would like to see them more easily.

If you go to Options > General > "Edit .ini file" button, then in moi.ini find this setting in the [View] section:

EditFrameOpacity=45

This can take a number from 0 (fully transparent) to 255 (fully opaque).

The default is pretty transparent to make them sort of "low overhead". Try something like EditFrameOpacity=150 and they should be more visible.
