Transparent window backgrounds?

[robwhitaker]

Is it possible to have transparent window backgrounds, such that you can see through to the desktop behind it? I tried setting the theme's clearColor to both transparent and rgbaHex "#000000" 0, but both resulted in a fully opaque window background.

Is there something I'm missing, or is this not possible?

Transparent window backgrounds are, in my experience at least, rather frustrating to work with.

I'm new to the project, but Monomer appears to use SDL under the hood. SDL does support transparent windows [1], but I'm not sure if this is exposed to Monomer. You could try checking the haskell SDL library documentation; there might be something useful there!

It's also worth considering that transparent window backgrounds rely on Windows' Layered Windows. I am unaware if this is possible at all on Linux or Macos systems.
