fix(hyprland): use synced rounding value when applying decoration

[enhulsman]

Problem

I noticed the Retro preset's square window borders weren't actually applying. Retro sets roundness: 0 in its theme config with syncRoundness: true, so Hyprland should get 0px rounding for sharp corners. Instead it was still using 16px rounding, giving rounded window borders that don't match the theme at all.

The issue is in HyprlandConfig.qml where syncRoundness is called to apply the rounding to Hyprland's decoration:rounding. It reads Config.hyprland.rounding (the raw Hyprland setting, always 16) instead of Config.hyprlandRounding (the computed property that checks the syncRoundness flag and uses the theme's roundness value when sync is enabled).

Solution

One-line fix: use Config.hyprlandRounding instead of Config.hyprland.rounding in the hyprctl batch command.

Config.hyprlandRounding is already defined in Config.qml as:

property int hyprlandRounding: hyprland.syncRoundness ? roundness : hyprland.rounding

So when syncRoundness is true (as in Retro), it uses the theme's roundness (0), and when false, it falls back to the independent Hyprland setting (16). The property was already there, it just wasn't being used in the right place.

Files Changed

• modules/services/HyprlandConfig.qml: use Config.hyprlandRounding instead of Config.hyprland.rounding

Testing

1. Apply Retro preset: window borders should be square (0px rounding)
2. Apply Default or another preset with syncRoundness: true and non-zero roundness: rounding should match the theme value
3. Set syncRoundness: false and change hyprland.rounding manually: should use the independent value
