As seen in the other screenshot I provided, changing the Opacity does nothing. 0 or 100 doesn’t matter.
I’ve reset tool options and uninstalled and reinstalled GIMP. Same issue persists.
I couldn’t find a .gimp folder anywhere.
Update
I fired up my old PC that has a 3 year old version of GIMP on it. No issues at all, created the box and modified my business card without an issue.
So - since reinstalling GIMP on this PC didn’t work and it seems to have loaded up with the same configuration as before, am I missing some files when I did the reinstall that I should have deleted?
