I'm trying to select a foreground object from a photo to remove the background using gimp 2.10.14. I am following these steps:
- rough outline of object using lasso tool
- press enter to enter foreground painting mode
- draw over foreground object
- enable 'preview' mode, looks good
- press 'select' button in floating window
But as soon as I press select the selection just becomes a load of vertical lines, see attached image
Just in case it isn't obvious the green wasn't part of the image! If I follow the same steps above but use the 'Matting Global' engine, then the selection is correct (although the results are not as good).
The settings I am using are:
EDIT - UPDATE
As per the comment from @user287001, I have attached another photo which is exhibiting the same issue.

A gif showing the steps I am taking is here: https://drive.google.com/open?id=1-xdV0LWtw-PJsgixFrMlxNcAxRfnVumh You can see that the selection looks ok in preview mode, but as soon as I press select the selection is completely wrong
I am sure it is me doing something wrong, but if anyone has any pointers that would be great!
