Black screen after login

[DataHearth]

Hello there!

I've updated swww from 0.8.2 to 0.9.5 yesterday, but now I encounter a problem (which seems to have be resolved and merge into the latest release but still occurs for me) with a black screen on login with a scaling monitor. I've never had this problem before and only occurs on one of my display (DP-2 which is 4k display scaled to 2 for visibility).

Anyway I can fix this?

Thank!

My setup:
OS: NixOS - Nixpkgs unstable
DE: Hyprland v0.41.1
swww: 0.9.5
Monitors:

• HDMI-A-1: 1920x1080, scale: 1, currently displaying: image: /home/datahearth/Pictures/assets/wallpapers/4.png
• DP-2: 1920x1080, scale: 2, currently displaying: image: /home/datahearth/Pictures/assets/wallpapers/4.png
  Init commands:

exec-once=/nix/store/2pz6jpcymjlbzbyi98vmwz9ssqx459r1-swww-0.9.5/bin/swww-daemon
exec-once=/nix/store/2pz6jpcymjlbzbyi98vmwz9ssqx459r1-swww-0.9.5/bin/swww img ~/Pictures/assets/wallpapers/4.png

EDIT: I've also tried with a different image format, same result

I have the same problem on Arch. I suspected it was due to the daemon taking a lot longer to start than the previous version. By prepending sleep 1 && to swww img it works, though it takes longer to set a wallpaper.

It would be nice if swww img launched the daemon if none exists so we can just issue one exec-once statement.

Gonna try this tonight! If it works, then that'll do for now. But it seems off to me that updating just one minor version add such a speed issue on daemon load.

From 0.8.2 to 0.9.5 is actually quite a jump. A lot of things changed under the hood.

I would also like to ask you to test this on the latest git version to see if the issue still exists there.

@LGFae Thank you for tip! I've tried using the latest commit and it is working. I'll check what has been done between 0.9.5 and HEAD ^^.
