2. write a unimported package method
3. ctrl+z
4. repeat step 2 and 3

Others

• Write typescript code, can not reproduce after write a unimported package method and undo. So, my guess is that the problem is caused by the vscode-go extension
• Disable all extension, the problem can not reproduce, becasue can not auto completed function.

I hope I have provided enough information

Thank you for this report. The problem is probably caused by the fact that the undo also removes imports, so maybe VS Code doesn't handle that well. The Go extension doesn't control which part of the screen is shown, so I'm not sure if this is actually caused by the extension--it seems likely that the problem is VS Code itself. Do you mind opening this issue up in the https://github.com/microsoft/vscode repository instead?

[elricli]

I opened this issue in microsoft/vscode.

Thank you! I'll close this issue, but please reopen if it does turn out to be a problem with the Go extension.
