Opening GPX file changes colours of ways

[Roger Calvert]

1. Open Josm
2. Download an area (screenshot 1)
3. Load a GPX file which lies within that area (20211119-2.gpx​)

Expected result: the GPX track should overlay the Data Layer, without changing it

What happens instead?

The ways on the data layer change to grey (screenshot 2)

This is a new behaviour - it occurs using track files which I have previously used successfully.

Deleting the track restores the colours to normal.

Please provide any additional information below. Attach a screenshot if possible.

I noticed little changes with default style, too, switching between wireframe and "normal" mapcss view.

I think I have found the solution to this. When the GPX file is loaded, it becomes the Active Layer, and the OSM data then appears in 'other colour'. Changing the active layer to the OSM data restores the colours.

This, to me, is a change in behaviour. Perhaps there is an option controlling it, but I have not been able to find it.
