After code is corrected and saved, previous error/problem is still persistent

[wileycoleman]

Describe the bug After correcting code to eliminate an error, and saving the fie, the previous problem and flagging of the problem does not go a way.

To Reproduce Make a simple type error in any code. For example use "string" instead of String. Save the file and see the proper error message and red underlining appear. Now change the code from "string" to "String". Save the file. The error message and red underlining do not go away. Close VScode and re-open it. The error message and underlining finally go away.

Expected behavior Once error is corrected and file is saved, the red underlining and error messages should go away.

Can you post the full output of the Crystal output channel?

The output tab is blank.

You need to select "Crystal" from the dropdown at the top right of the panel

The above is from changing "String" to "string" then back. (saving file in between actions.)

Thank you. In the meantime for things to work you can disable a lot of the features to just use snippets and syntax highlighting. Check this repo's README for more info

I've also run into some weird ghosting with Crystal sometimes recently. Does it still happen if you try building from the command line? crystal clear_cache may help.
