Hi 👋

I am trying to package Budgie 10.10 (and budgie-desktop-services 1.0.0) in NixOS. When testing, I noticed that changing DPI scale in wdisplays 1.1.3 does not update ~/.config/budgie-desktop/display-config-shim.toml, while updating Size works fine.

Steps to reproduce

Open wdisplays.
Only change Size, then apply the changes.
cat ~/.config/budgie-desktop/display-config-shim.toml (looks good!)
Only change DPI scale, then apply the changes.
cat ~/.config/budgie-desktop/display-config-shim.toml (oh no)

This is the journal when I only update Size and then Apply the changes:

Jan 12 22:37:37 thinkbook org.buddiesofbudgie.Services[2910]: Head current mode changed to:  0x7f9918002ed0
Jan 12 22:37:37 thinkbook org.buddiesofbudgie.Services[2910]: Current mode changed for output:  "0x00006002"
Jan 12 22:37:37 thinkbook org.buddiesofbudgie.Services[2910]: Setting current mode to 3200 x 2000 @ 60000

Jan 12 22:37:37 thinkbook org.buddiesofbudgie.Services[2910]: OutputManager::zwlr_output_manager_v1_done with serial: 17818

This is the journal when I only update DPI scale and then Apply the changes, it looks like budgie-desktop-services is aware of the scaling changes (and the scale does change) but the state is not written to the toml file.

Jan 12 22:40:55 thinkbook org.buddiesofbudgie.Services[2910]: Head scale changed to:  2
Jan 12 22:40:55 thinkbook org.buddiesofbudgie.Services[2910]: Setting scale on head "0x00006002" to 2
Jan 12 22:40:55 thinkbook org.buddiesofbudgie.Services[2910]: OutputManager::zwlr_output_manager_v1_done with serial: 24727

This is the generated display-config-shim.toml:

[preferences]
automatic_attach_outputs_relative_position = "none"

[[group]]
name = "0x00006002 (Auto Generated)"
preferred = false
identifiers = ["0x00006002"]
primary_output = "0x00006002"

[[group.output]]
identifier = "0x00006002"
width = 3200
height = 2000
refresh = 60000
x = 0
y = 0
scale = 1.0
rotation = 0
adaptive_sync = 0
primary = true
disabled = false

Let me know if more info is needed, thanks!
