Hi. I had the same problem and a quick GPT chat suggested and it solved the problem.
1. Drag/drop or attach the PNG file into TheBrain instead of Ctrl+C/Ctrl+V. That should preserve the file's alpha channel.
2. If you're copying from a browser, save the image first and then drag the saved PNG into TheBrain.
3. If you're converting SVG → PNG, make sure the converter outputs an actual transparent PNG.
4. Test copying the exact same PNG from different programs — e.g. Windows Explorer, Paint.NET, IrfanView, browser — and see which one causes TheBrain to turn transparency black.
