[BUG] Stretchly spawns a lingering process on each break

Description

I looked at task manager and noticed there are hundreds of stretchly processes. I closed and restarted stretchly. I see there are a few Stretchly.exe in task manager, and on each break a new process is spawned.

Operating system: Windows 10 20H2

Steps to Reproduce

1. Open task manager. Count how many Stretchly.exe there are.
2. Right click on stretchly tray menu and skip to next break.
3. Repeat step 2 while watching number of stretchly processes in task manager goes up.

Expected behavior: Number of stretchly process (and memory usage) remains roughly constant.

Actual behavior: Stretchly keeps spawning processes.

Reproduces how often: 100%

Hi, that's how electron works. Stretchly is built with electron.

[Anonymity]

Ouch. So I need to manually restart Stretchly regularly to avoid memory leak?

[hovancik]

I might be wrong but I don't think it is a memory leak. Look for example on Slack or other electron based apps, they have many processes as well.

[Anonymity]

Having many processes isn't a problem if it doesn't grow. But in stretchly's case it starts off with 4, then goes up by 1 every break. I rarely reboot so over time there are literally hundreds of processes.

[hovancik]

Ok, I don't have Windows but let me try on Linux. Just quited Stretchly, started again and I have 8 processes running. We'll update later if I don't forget.

I am doing regular close() so if there is a issue, it's probably electron

• https://www.electronjs.org/docs/api/browser-window#winclose
• https://github.com/hovancik/stretchly/blob/trunk/app/main.js#L222

update: also on Linux

[hovancik]

Not sure if same, will have to read later, but quick search finds this: electron/electron#21586

Facing the same problem on windows, new process gets spawned after every break.

[XuhuiSun95]

I think it has some sort of memory leak issue.

For me on Linux - ubuntu 20.04, snap version. I also experience the VRAM leak issue.
The application will eat up all the VRAM slowly. I have not experienced this issue at version 1.4. but it happens in 1.5 and 1.6.

I get the same issue with .deb version of Stretchly v1.6 installed in Ubuntu 14.04 and 16.04 LTS, it spawns after each break and uses ~3GB memory . It seems harmless to manually kill the spawned processes.

[jmagaram]

I get this too on Windows 10.

[TrutzX]

Hello,
I love the app. Have now updated to the 1.6. Every time a break starts, a new process is started on each monitor. But the old processes are not closed. One process consumes 19 MB Ram for me, so 10 min break * 3 monitor * 19 MB = 350 MB Ram per hour * 10 hours => 3,5 GB Ram per day extra.

Emergency solution:
A cronjob on my ubuntu kills stretchly daily and then restart stretchly.

[hovancik]

Sorry guys, but looks like noone is working on this on Electron's side: electron/electron#21586
