Animations consume MUCH CPU

[miccl]

Hi,
while using your useful module, I noticed that MM uses a lot of CPU. After some digging, I found out, that the cool animated icons of your module are the reason. If the animations (currentIcon and weatherForecastIcon) are activated, the CPU usage ascends by > 50%).
Do you have any idea why this error occurs?
I deactivated the animations for now, but would love to use them again.
Thanks in advance

Hi Michael,

thanks for opening this issue. I experienced a similiar problem when using the animated icons. In my case, the whole MagicMirror app crashes after some hours (approximately 24 +/- x hours). I'm pretty sure it's the Electron browser who crashes, because the "backend" is still available (e.g. the MMM-Remote-Control plugin). In the pm2 logs I can see an error message like "out of memory [...]" without any specific stacktrace or anything else.

I tried to debug the problem with Chrome DevTools, investigating heap dumps and memory timelines, but without any success. I ended up using static icons too, but this is unsatisfying 😔

If you have any further informations, please let me know. I really want to solve this problem, because I like the animated icons on the mirror. But this will probably take some time to debug it again and I can't predict any result ...

Hi Nikolas,

yep. You describe exactly what I experienced as well. Sadly I only saw the same bland error message.
But if I have a free minute and find something, I will let you know.

Have you tried to use a new Electron version with the Chromium updates?

Hi Aleksander, I update my MM regularly but didn't try the animated icons for a long time. Even static icons aren't displaye currently so I think the whole icons are broken anyway. Maybe I should give it a try ...

The static icons work fine for me with 2.21.0.
