I installed the new version 3.0.4 and immediately encountered a problem with perspective transformation. It leaves black areas that should be transparent, leaving the background layer visible.
Could anyone point me to a solution? This wasn't an issue in the old version, so I hope it's just a matter of changing the settings.
Thank you for your help.
You need to add an alpha channel - Layer -> Transparency -> Add Alpha Channel
Edit: What can you do in Gimp 3 - Edit -> Preferences -> Image Import & Export -> enable add Alpha channel......
Edit: It looks like this is fixed but you will have to wait until Gimp 3.2 ( works as per Gimp 2.10 using the development version Gimp 3.1.2)
oh..dear...the devs are still considering what to do
