A user opened an issue reporting that rounded corners (border radius) unexpectedly appeared across multiple VS Code surfaces after launching the app. Using VS Code 1.139.0 (Universal) on OS version 26.5.1 (25F80), the reporter says the editor, file explorer, terminal and Copilot chat all display prominent border-radius styling that distracts and reduces productivity. The report includes a simple reproduction: open VS Code and observe the rounded corners; extensions were disabled when tested, so the problem persists with extensions off.
The issue, created by Wes Coderre (kidCaulfield) on Sep 25, 2026, was assigned to hawkticehurst and later closed as a duplicate. The report emphasizes the visual regression as a widespread “infection” of border radius into desktop UI components and asks for help reverting or fixing the styling. Metadata shown on the issue page (labels, assignee, project/milestone absence) and a note that reactions and commenting require signing in are included, but no technical root cause or workaround is provided in the original report.
