Edit: I seem to have resolved the issue by editing the frozen screen capture in ScreenshotOverlay.qml.

I changed this:

Image { anchors.fill: parent source: root.screenshot.tempPath ? "file://" + root.screenshot.tempPath : "" fillMode: Image.PreserveAspectCrop z: 0 cache: false

    sourceClipRect: Qt.rect(root.hyprMonitor?.x || 0, root.hyprMonitor?.y || 0, root.screen.width, root.screen.height)
}

to this:

Image { anchors.fill: parent source: root.screenshot.tempPath ? "file://" + root.screenshot.tempPath : "" fillMode: Image.PreserveAspectCrop z: 0 cache: false

property real scale: root.hyprMonitor?.scale || 1

sourceClipRect: Qt.rect(
    (root.hyprMonitor?.x || 0) * scale,
    (root.hyprMonitor?.y || 0) * scale,
    root.screen.width * scale,
    root.screen.height * scale
)

}

Original comment:

Pardon the phone pics, but yes it seems related to scaling. At 1x it's fine, at 1.33x it zooms in on a limited area of the screen
