I am Getting Severe Text Corruption in an Application when Magnified

Text corruption can occur for a variety of reasons. For example, the application being used may not have been fully tested, or it may have recently received an update. This is most commonly seen in Microsoft Office applications.

TrueFonts corruption comes in 2 forms:

Overlapping Text

Pixelated/Static Text

When TrueFonts corruption is identified, it should be reported to the Dolphin Support team. If the issue is caused by a software update, changes may need to be made to SuperNova to ensure ongoing compatibility.


Workarounds

There are several workarounds that can be used to mitigate TrueFonts corruption while a permanent fix is being developed and tested:

Cycle Text Smoothing Options

We first recommend switching between the three font smoothing options to determine whether one provides a better experience. The available options are None, Standard, and True Fonts.

These settings can be found in the SuperNova Control Panel > Visual Menu > Advanced Options > Magnifier property sheet. Alternatively, you can cycle through the options by repeatedly pressing Left Ctrl + Numpad 8.

Configure the Magnification Engine

Until a permanent fix is available, users can switch to the Alternative Magnification System. In some cases, using this setting can prevent TrueFont corruption from occurring and provide a more stable magnification experience:

  1. Open the SuperNova Control Panel by pressing CTRL + SPACEBAR.
  2. Press ALT + G to open the General menu.
  3. Navigate to and select Advanced Options.
  4. Within Advanced Options, open Magnification Engine Settings.
  5. Select the Alternative Magnification System checkbox to enable the alternative magnification engine.
  6. Test magnification again to verify that the issue has been resolved.

Change Office Channel (Only applicable to Office applications)

If the issue is present in an Office app we recommend temporarily switching your Microsoft 365 Apps update channel to the Semi-Annual Enterprise Channel. This channel receives updates less frequently, helping to reduce the impact of recent Office changes and providing a more stable user experience.

The delayed update schedule allows additional time for issues to be identified and resolved before updates reach your device. Once a fix has been released, the update channel can be switched back to its original setting.

For more information about switching the Office channel, please see the relevant Microsoft page:  Change the Microsoft 365 Apps update channel for devices in your organization - Microsoft 365 Apps | Microsoft Learn 

Registry Editor Changes

The final workaround involves making changes through Registry Editor. You can manually create exclusion entries in the Windows Registry to prevent SuperNova's dol_hook module from attaching to an application's processes.

To do this, create the following registry keys, replacing APPLICATION with the relevant process name. For example, use WINWORD.EXE for Microsoft Word:

Key 1:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Dolphin\dol_hook]

[HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Dolphin\dol_hook\APPLICATION]
"interfaces"=dword:00000000
"functions"=dword:00000000
"process"=dword:00000000

Key 2:
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Dolphin\dol_hook]

[HKEY_LOCAL_MACHINE\SOFTWARE\Dolphin\dol_hook\APPLICATION]
"interfaces"=dword:00000000
"functions"=dword:00000000
"process"=dword:00000000

Disclaimer: Dolphin Computer Access Ltd. cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Before attempting the following, create a backup copy of your Windows Registry and a system restore point. Failure to do this may result in a non-recoverable system.
