Zed becomes unresponsive and stuck on 100% CPU utilization every hour or so

[mcobzarenco]

Summary

I have been using Zed for over a month now, I love it when it works, but currently the editor ends up hanging regularly, roughly every hour or so.

Actual Behavior:
Every hour or so, Zed gets stuck in a completely unresponsive state (including no redraw of the Vulkan surface) on 100% cpu utilization.

Expected Behavior:
No hangs or getting stuck on 100% utilization while being completely unresponsive.

Thanks for reporting. There are definitely some issues with Zed gracefully recovering from certain GPU events.
