Google Chrome is regularly updated with new features and UI changes, as a new build makes it way to the Stable channel every four weeks. While the browser's current design language emphasizes sharp edges and corners for UI elements, it appears that work is being done to enable rounded corners in menus to align with Windows 11's design language.
As spotted by Reddit user Leopeva64-2, a new patch to the Chromium Gerrit indicates that some configuration changes are being introduced to enable menus with rounded corners for Chrome in Windows 11. The change owner Allan Bauer has stated that the code for this has already been written but has been commented out for now so it is not yet merged with the Windows 11 menu feature flag. This makes sense as the OS is not even generally available yet. However, based on the comments in the code, the menu redesign will be available across all versions of Windows. A snippet of the code in question can be seen below:
Bauer has noted that this commit is not the final implementation and is still very much a work in progress. He went on to say that:
This is admittedly not the prettiest solution to implement Win11 style menus, but we're short on time. I'd like to eventually change the menu code to do full config with the menu_config without all the added conditional checks sprinkled throughout the code.
As such, it is currently unclear when the final implementation of menus with rounded corners will be ready for consumption on Windows, provided that it does pass all checks to make its way to Chrome Stable. Microsoft Edge on Windows 11 already sports rounded corners with acrylic effects.
