fancy-splash-image background not transparent with svg image

[bryanhonof]

What did you expect to happen? I expected the dashboard image to be transparent when setting the fancy-splash-image to an svg with the following code.

(setq fancy-splash-image "~/.config/doom/Emacs-logo.svg")

What actually happened? The actual image is displayed correctly but with a white background instead of a transparent one. I also checked the Messages buffer but nothing of note is found in there.

Is this know behavior? If so I would be willing to update the documentation making user aware of this. If not, could it have something to do that I am running NixOS? The svg I am using can be found over here

Ok, the plot thickens. When evaluating the piece of code in buffer with C-x C-e, (yes I use the default emacs bindings, forgive me for I have sinned) And than opening the buffer with +doom-dashboard/open it does display the image with a transparent background instead of the white one. When I restart emacs however, it goes back to the one with the white background.

However, in the Messages buffer there seems to be nothing of interest.

I suspect this may be an upstream issue (with Emacs 28). I cannot reproduce this on Emacs 27.1.

@bryanhonof Also experiencing this on Emacs 28, however you don't need to evaluate code with C-x C-e, switching to another buffer and back to the splash-screen is enough to make the background transparent.

Honestly not quite sure what ended up fixing this. But, I haven't noticed this behavior for quite some time now. So I think it's time to close this issue :).
