Stremio using too much RAM and freezing Ubuntu

[AXL1994]

Describe the bug I'm using Stremio (Flatpak version) on Ubuntu 21.04. When I watch a series, Stremio start the next episode when I finish the previous one. When I watch the first episode everything is ok, Stremio and Ubuntu are very smooth, but when the next episode start, everything start to freeze and lag.

The RAM is saturated, like if Stremio is keeping in memory the previous episode. It makes the computer unusable, and I have to force shutdown because it's so unresponsive that I can't click the shutdown button.

To Reproduce Steps to reproduce the behavior:

• download the flatpak version to Ubuntu
• start an episode
• when it's at 100% start the next one

You will see that the RAM keeps being filled, until the computer is unusable.

Expected behavior The movie/series should be cached on the hard disk, instead they are cached on RAM without any limit

Desktop (please complete the following information):

• OS: Ubuntu 21.04

Hi, Could you please tell us how did you install stremio? Was it with flatpak package?

Yes, it was a flatpak package. In the past I tried the .deb file from the site, but I had some problems installing it, so at the end I used the flatpak package, it's much easier to install. So I can't tell if the problem is present also in the .deb version, in the flatpak is present for sure. I use Ubuntu with only some Gnome extentions and nothing more, I use it mostly as a media player.

@TRtomasz In the meantime I changed distro, I installed Fedora 34 and installed the Flatpak package as well, but the problem is still here. I searched on the web about memory leaks with node.js, because it fills up a lot of RAM, and I found this link where they are talking about a memory leak with PM2 on: https://github.com/nodejs/node/issues/38120

I don't know if it's useful, furthermore the flatpak package is outdated at the version 4.4.137, so maybe in the 4.4.142 version the bug is fixed.

@AXL1994 thanks for the update. @core1024 could we do anything with this? I'm pretty sure that leak is somehow caused by flatpak.

Am experiencing this on Fedora 37 Silverblue with Flathub version of Stremio. Ram just fills up, my hunch is that the media watched stays in RAM for some reason.

Same here. Flatpak version. Used to happen almost every time I used Stremio, filling all my memory up and freezing the whole desktop, almost never happens now that I set up zram (which more than doubled my available memory) but the slow downs still happen and it froze my desktop again once since I set set up zram.

I think this is the root cause also of the app causing restarts on LG WebOS TV's and Firestick devices also. I think the app is no cleaning the buffer of watched media until the media is done, this is a problem when almost all Full HD content today has more then 1GB of size, smart tv devices has low memory and this turn the app unusable in these devices
