Most likely, you are using VisualGDB with clang-format. Please try clicking on the “format document” icon in the top right corner of the text editor (near the “go” button). It will open a detailed editor for the clang-format style file.
Thanks for the screenshot. Looks like you are using the legacy formatter, so the clang-format settings are irrelevant.
We have double-checked the configuration you mentioned. The option you mentioned controls an extra newline between “{” and “}”. In order to control whether “{” gets on a separate line, please use the “New control blocks” option instead.
