I'm not sure :) It does have some impact, e.g. because creating a new layer will use this crs (if it's done before any other layers are added). I suspect this is one of those settings which has been around for so long that it just no longer has any real meaning. Maybe it's a relic from before OTF was introduced? The options I can see are: 1. Remove the setting, always start new projects in EPSG:4326, and then switch to match the crs of the first loaded layer 2. Remove the "set project crs to match first loaded layer crs" feature, and always start new projects in the crs defined by that setting. Loading layers doesn't change the crs. We need to proceed with caution here. For reference, I'd be a hesitant +1 to option 2.

If there is a bug to file, it should be that if you click Cancel, it still loads the layer On 25/07/18 02:50, DelazJ wrote: Hi, In the Settings --> Options --> CRS menu, user can choose a CRS which is used as default whenever he opens a new blank project. Then if he adds a layer: - if the layer CRS is different from the one I set for the project, the project CRS is changed and aligned with the first loaded layer CRS; - if it's a geometryless layer, then the project CRS is set to epsg:4326 Then, my question is what's the interest of setting a default CRS for all projects, if each time I open a new project it's the first loaded layer that dictates the rule and applies its CRS?
