Partial transparency of default-bg ignored
Issue description
(Running Zathura under Wayland)
To reproduce: :set default-bg "rgba(255,255,255,10)"
Expected result: a background that is slightly white, with my wallpaper shining through.
Actual result: a fully white wallpaper.
Alternate case :set default-bg "rgba(255,255,255,0)"
does work as expected, and my wallpaper comes through completely: https://i.imgur.com/MantekM.png
Alacritty on Sway does support regional partial transparency, so it doesn't seem to be a Sway issue.
