Splashscreen transparency does not work on Linux

[jeffdod]

I'm building an Electron.NET app for Windows, Mac, and Linux. On Windows and the Mac, my .png file with transparency works fine as a splashscreen when specified in the electron.manifest.json file under the "splashscreen" : "imageFile" option.

However, on Linux (specifically, Ubuntu 21.04), although the splashscreen displays, the transparency in the .png file is not observed, and instead I see a black background where the transparency should be.

I looked at other splashscreen examples on the internet, and I also looked at the various options in the electron-builder documentation, but didn't see any way to tweak this for Linux.

Are transparent .png files allowed on Linux as the splashscreen images?

This is an electron issue. Not sure if this is the original link when I found it last year or not but don't see it being fixed soon.

Thanks. Yeah, I'm not going to hold my breath waiting for this one to be fixed, based on what I saw in that thread.
