OpenCode - Fails to close instance.

[pnpancholi]

Description

System: Lenovo Thinkpad running Ubuntu LTS

This issue has been happening quite a bit and I did not notice it until recently. Whenever, I close OpenCode it closes the window but the instance keeps on running in the background. I noticed this when my memory usage went to 95% with just a couple of browser tabs while I have nothing else running. So, I checked my resource monitor and noticed that OpenCode had 11 instances running.

I was wondering if other people are facing this too. If so, I would be happy to look into it and contribute to solving this problem myself. I am just curious about collecting more data on this.

Thanks.
