Ghost UI Artifacts on 4K Displays When Using Windows Graphics Capture in SuperNova 25

Overview

Users running SuperNova version 25 on high‑definition 4K monitors may experience ghost UI artifacts when using the Windows Graphics Capture magnification engine. This issue can cause faint or greyed‑out outlines of previously opened applications to remain visible on the screen while panning the magnifier.

This behaviour is a known issue and is currently under active investigation by our development team. Tracking number: OT50753

Symptoms

Affected users may notice:

• Faint, ghost‑like outlines of application windows

• Greyed‑out remnants of UI elements that remain stuck on the screen

• Artifacts appearing specifically when panning the magnification view

• Issue occurring only when using the Windows Graphics Capture engine on 4K displays

Cause

The issue appears to be related to how the Windows Graphics Capture engine interacts with high‑resolution 4K displays when SuperNova’s magnification is active. This behaviour is not limited to a specific device type and may occur across desktops, laptops, and tablets.

Workaround

Until a permanent fix is available, users can switch to the Alternative Magnification System, which does not exhibit this issue.

Follow these steps:

1. Open the SuperNova Control Panel using CONTROL + SPACEBAR

2. Open the General menu with ALT + G

3. Navigate to and select Advanced Options

4. In the Advanced Options menu, open Magnification Engine Settings

5. Tick the checkbox for Alternative Magnification System to enable the alternative engine

6. Retest magnification to confirm the issue is resolved

Switching to the alternative engine should prevent ghost UI artifacts from appearing.

Status

This issue remains under investigation. Updates will be provided as soon as a fix is available.

If you face this issue please contact Dolphin support and provide your device specifications including your device model number/version.
