The red dot does not disappear when the mouse quickly slides from the editor page to the left page

[xiaguangbo]

vscode itself has no debugging function for .c files, and there is no red dot on the left side of the editor's line number

After installing the C/C++ extension, under normal circumstances, when the mouse moves to the left of the line number, a dark red dot will appear. When the mouse continues to move left beyond the editing page, the dark red dot will disappear, but when you quickly swipe across, there is a chance that the red dot will not disappear

It sounds like you're describing a UI bug with VS Code. Our extension doesn't implement any of the UI layer which could cause UI bugs. You should file a bug at https://github.com/microsoft/vscode/issues .
