DefinitionBase holds many calculation and status of groups, especially SharedSizeGroup, i doubt if this is even possible.

similar https://github.com/AvaloniaUI/Avalonia/issues/14711

https://github.com/rabbitism/FontDiffIssue https://github.com/rabbitism/AvaloniaIssueRepro/tree/main/FontRenderIssue Here is the repro, run both projects and compare closely. 

You need to upgrade to 11.0.10 instead of 11.1beta

11.0.**10**

nuget version has nothing to do with extension. just open your csproj file and edit every version related to Avalonia to 11.0.10.

And using nuget manager you can choose the version here 

When I say every, I mean every. Your desktop, android, ios and browser project is still 11.0.2

Is this specific to Ursa or all cases?

AvaloniaEdit mostly uses Avalonia built-in controls so it's is compatible to use Semi.Avalonia and AvaloniaEdit fluent theme together. I remember there were two resource keys missing, you can add them...
