View Designer the richtext is incorrect font format

[Neng]

Hi, I’m using VB.NET and displaying RichText content in my report. The RichText value is stored in an NVARCHAR field, which saves the text in RTF format.

However, one client is facing an issue where the font displayed in the report is different from the RTF formatting we set.

When we back up the same database and view it on our PCs, it looks normal. The issue only occurs on the client’s PC.

Client side:

Actual result:

Client environment:

Windows 10 Enterprise LTSC

My environment:

Windows 11 Home Single Language

both is Stimulsoft version: 2025.3.4

The client has already reformatted the PC, but the issue remains. We also verified that the font used in the RTF is installed on the client’s machine.

Does anyone have any suggestions or know what might cause this issue?

The way we use the rich text:

Hello,

Check whether system scaling affects it.
If your code uses StiOptions.Engine.CheckInstalledPrintersForRichTextMeasureGraphics = true;
Then don’t use it and leave it as "false" by default.

Also, check whether the behavior changes if you set Wysiwyg = false for the component, on some computers, it glitches when Wysiwyg = true.

Thank you.

Hi,

as check, we did not use StiOptions.Engine.CheckInstalledPrintersForRichTextMeasureGraphics = true
and already set to Wysiwyg = false but still same.
