Memory overflow + silent app crash or OS crash

[systemoperator]

Is there an existing issue for this?

Current Behavior

When I start Spotube, there is a tremendous, greedy memory consumption after a while, starting to consume all available GBs of memory, including swap space. I guess, this is also the reason, why it silently crashes after a while, or my OS hangs/crashes, because there is no memory left. In the system monitor, I could see, 17 GB were currently used by Spotube, still increasing rapidly. I had to kill the Spotube process, otherwise my system would have crashed. The last time, this happened even when no music was playing, Spotube was just running in the background.

Expected Behavior

I would have expected less memory usage, even less than Spotify.

Steps to reproduce

1. Start Spotube
2. Just wait.

Operating System

Linux Debian 11, 64-bit, Mate desktop

Spotube version

2.7.1

Installation source

Flathub (Flatpak)

@isle9 mentioned in #442 (comment)

Spotube memory consumption seems to skyrocket after a few minutes. I saw it go up to 14gGB.

Remark: Notebook has been suspended sometimes.
