Does this happen consistently? Were you doing anything in particular? We haven't really gotten any other reports of a memory leak or a stack overflow, so this is very unexpected. Unfortunately, I'm not sure "Windows Problem Reporting" reports the issue anywhere we have access too - or if it did, I'm not sure we'd ever be able to find your specific crash.

maybe it was just a random bit flip who knows ¯\_(ツ)_/¯

Yea, if this isn't happening consistently, then I'm not sure there's anything more we can do here. I'm sure if this was widespread, we'd have plenty more reports. If this was even something that was consistent on your machine, then we could determine if a bugfix solved your issue. As it is though, there's nothing consistently causing the issue, so we can't even be sure any code change will fix this.

Do make sure to let us know if this happens again though!

Don't know if you guys are testing your code - but I see 600MB+ private bytes as well and it doesn't get reduced if a tab is closed. VmMap shows that most data is history not cleared from heap.

@webloft What are you doing in the Terminal that's getting to 600MB? I've got a Terminal window sitting here with like 10 open panes, and it's sitting at 137MB. Any chance you're like, saving the SUI a bunch of times?

I am monitoring output messages of a daemon several hours in one tab and in another one I'm executing some batch scripts. From my observations the main application is allocating:

  • by output appending (it adds 4K each at some cycle)

  • by doing actions on the UI Window, eg. moving the Window seems to allocate without cleaning up (adds ~20K)

I also had the same issue as the first comment said, a spike in ram usage of windows terminal (stable version), about 3GB after keeping it minimized for about like an hour, I only had two tabs opened , one tab had neovim 9.0 dev(recent dev version from winget) and the other just cd to a directory, as for others i had edge and vscode opened. Sorry I don't have a screenshot as it crashed and i had to restart, I thought I should let you know
