GIMP - 3.0.4 - perspective transformation - MichalStanczyk - 07-09-2025

Hi everyone

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 Wink
