@zafersn This may be a VS Code client bug because it's an issue with what appears to be reloading of the theme colors.

Could you try uninstalling the C++ extension pack and the C++ extension, but only retain the C++ themes and see if it still flickers? Does this only happen with certain theme colors or only for the dark themes?

sean-mcmanus commented 2 years ago

This is a duplicate of https://github.com/microsoft/vscode-cpptools/issues/9689 -- we're not sure exactly how to repro it yet, but it seems like removing the duplicate files.associations should fix it. Maybe another setting is required to be set.

sean-mcmanus commented 2 years ago

Also, I'm seeing "Connection to server got closed. Server will not be restarted" (i.e. cpptools process crash) but that could be completely unrelated...let us know if you have any more info on that repro.

zafersn commented 2 years ago

Hi @michelleangela in some cases I need to use c++ extension and pack. So I believe it is not the solution. but anyway, I disabled those extensions and tested. yes, it worked for me and I didn't see any flickers. But the thing is I have come across an issue like that only in this piece of code, not in any other files. I was wondering why?.

And also, I came across a few times there were no flickers on that header file when I was switching between pages, although all c++ extensions were enabled

michelleangela commented 2 years ago

@zafersn It could only be happening to that particular file due to some IntelliSense parsing issue. Could you provide the following logs when the flickering happens? The logs will show operations IntelliSense is doing and how it's configured.

Logs from running C/C++: Log Diagnostics from the VS Code command palette
Logs from the language server (see https://code.visualstudio.com/docs/cpp/enable-logging-cpp#_enable-logging-for-the-language-server)

This issue has been closed because it needs more information and has not had recent activity.

sean-mcmanus commented 1 year ago

The fix is available with 1.14.0 (pre-release): https://github.com/microsoft/vscode-cpptools/releases/tag/v1.14.0
