Intermittent Custom Font Loading Compatibility Issues

Update
We have determined that the previously implemented fix for fonts loading has not fully resolved the issue. Our team is actively working on an alternative approach and has engaged Microsoft Support to assist with further investigation.

We will provide another update as soon as more information becomes available.

Custom fonts have now been re-enabled across the majority of our terminal servers, and most users should be able to access these again. We will continue to closely monitor platform stability and complete the remaining rollouts throughout the week.

In collaboration with Microsoft, we have confirmed the issue is related to a compatibility interaction between custom font loading and the latest Windows Server. Updates to VETtrak Desktop have been put in place to resolve this.

The application update has been deployed, and we are progressively adjusting the platform policy that controls custom font loading across the hosting environment. We will continue to monitor stability as changes are rolled out.

We are currently investigating a compatibility issue related to the loading of custom fonts on our systems running Windows Server 2025.

In some scenarios, the use of custom fonts can cause instability on affected servers. Our team is actively working through this issue and engaging with Microsoft to identify the root cause and a permanent resolution.

As part of our mitigation efforts, we may temporarily limit the use of custom fonts to ensure overall system stability while we continue our investigation.

We will provide further updates as more information becomes available. Thank you for your patience.
