Describe the bug

To Reproduce
Steps to reproduce the behavior:

1. Start Desktop App in Windows.
2. In Settings, change "Run in background" to No
3. Close app.
4. After closing app, 3 background processes will remain.

Expected behavior
That all processes quit

I'm experiencing the same issue but on Linux (Fedora 41)

Tuta Desktop Version: v259.241223.2

After closing the Desktop app completely, one process (tutanota-desktop) remains running and causes the fans of my laptop to spin on full speed. Only after manually killing the remaining process the fans will slow down again.

Same here, on macOS 15.2.
(Desktop version 259.241223.2)

same issue Windows 11 (Tuta [259.241223.2 Desktop)

Same thing on Ubuntu 22.04. Tutanota desktop appimage v259.241223.2
Each instance is taking a significant amount of cpu to the point where if I have 10 of them my machine becomes quite slow. I tried leaving it for 12 hours or so and they never finished or closed whatever they were doing/waiting for.

Same here endeavour os (arch) and Tuta desktop 259.241223.2
Tuta desktop Integrated but not set to run in background.

Tuta stays in background and occasionally (half the time) uses high cpu. Have to manually KILL

Same issue, I don't normally leave Tuta running (I launch it when I need it), PC was crawling, restarted, opened Tuta and closed it but saw multiple tutanota-desktop processes were still running when checking htop with 1 tutanota-desktop process eating 1 CPU core at 100% even 15 minutes after closing the app.

A fresh PC reboot or not makes no difference, I launched Tuta again, closed it after it logged in and did it's new message check, now there's 2 tuta processes eating 2 CPU cores at 99/100%. SigTerm doesn't stop them, only SigKill and launching a new Tuta instance then closing it the issue repeats again.

I'm on the latest EndeavourOS using the Tuta desktop appimage v259.241223.2.

Run in background: No
Run on startup: No

This issue seem to occur in versions >= V259.241223.1
Logs from a Mac were provided in #8199 (comment)

The behaviour is a slightly different, it was well represented in a previous post which is now closed (#8210) The application does not quit, you have to force quit. This seems to be a macOS only bug. I'm on 12.7.6, but it seems to happen on all Macs systems.

I was wondering why my laptop was so loud and discovered Tuta being the culprit. I tried to recreate it: After opening and closing Tuta Desktop four times, I watched all instances first go down to 0 % CPU usage and after some time one became active again, rising to around 20 %. A short while later another became active and they started to show the same activity pattern (rising and falling in sync between 17 and 22 % CPU usage). Probably the others would also become active, if I gave them more time, but I'm not sure whether they would stop or pause by themselves.

V259.241223.2 on Windows 11
Run in background: No
Run on startup: No

259.241213.0 (Desktop) Is the latest version which reliably quits all processes for me.
