Description
Type: Bug
使用一段时间后,鼠标移到变量或者typescript类型上面,会有以下问题:
- 没有类型提示,没有任何反应,此时按住command同时点击鼠标左键可以正常跳到实现
正常会有浮层提示类型,重启VS Code之后正常,但是使用一段时间之后还会出现
After using it for a while, when you move the mouse over a variable or typescript type, the following problems will occur:
- No type hint, no response, at this time, hold down command and click the left mouse button to jump to the implementation
Normally, there will be a floating layer prompt type, it will be normal after restarting VS Code, but it will still appear after using it for a while
-
Normal display
The mouse pointer is at the arrow position

Research direction
Start by reproducing the missing hover type hints in VS Code 1.96.0-insider on macOS after extended use, using the reported TypeScript context and installed extensions. Compare hover behavior with command-click navigation, and verify whether restarting VS Code restores the hints. Done means the cause is isolated and hover type information remains available after the reported usage period.
