1 year ago Yes, rust-specific on my local development environment at least. It happens even when all the VSCode extensions are disable.
However, this screen flickering doesn't always occur. Thus, it's hard to reproduce consistently. (Unfortunately, it doesn't occur right now while I'm writing this comment...) It's entirely possible that it's not rust-specific.
But, this screen flickering always occurs in the window where I'm writing code on Rust project. Even if I have multiple windows open, including Rust projects and, for instance, TypeScript and Go projects, the flickering always occurs only in the window with the Rust project.
Lately, this has been happening frequently while I'm working, and it's been distressing. I'd be happy to help, so could you tell me how to investigate this phenomenon on VSCode? What should I pay attention to the next time this phenomenon occurs?
Let me know if you need any more information.

1 year ago Can you provide the output of system_profiler SPDisplaysDataType. Do you have a multi monitor setup or using something like https://github.com/waydabber/BetterDisplay to get HiDPI ?

1 year ago I am using two external monitors with FHD and 4K resolutions. I'm not sure if it's related, but I am using an application MonitorControl to control display settings with DDC protocol, which might be similar to BetterDisplay (see a screenshot below).
Result of system_profiler SPDisplaysDataType is the following:
