There's a similar issue here, but I can't reproduce it using its configuration (SDK 10.0.100).

@claudiaregio You can watch this video.

@v-reinawang thank you! That’s a lot worse than what I imagined from the text. For clarity, this is only happening for you with latest stable release and .NET 11?

[v-reinawang]

@claudiaregio This issue only repro with .NET 8.0, not repro on .NET 9.0/10.0/11.0. And only repro on latest stable release C# Dev Kit(3.10.4).

@v-reinawang Thanks sorry I misread. I'm not able to reproduce this on Mac, could be a Windows-specific issue. Are you seeing the same thing on pre-release version of C#DK? If so, could you open the command palette and run ".NET: Collect C# Dev Kit Logs" and paste the zipped folder here? (This command is not yet available in stable so if you only see it in stable you may have to manually open the C# Dev Kit logs in the output pane)

[v-reinawang]

@claudiaregio I did not reproduce with pre-release C# DK 2.13.12 (C# 2.131.79).

Below is the log information from the C# Dev Kit output panel when using the stable version.
