Weird bug in SMPlayer Version: 20.6.0 (revision 9418)

[Stefanos Sofroniou <sofr.stef@cytanet.com.cy>]

Greetings and happy new year.

I'm using SMPlayer with MPV as my backend.

I play an entire playlist and when it starts, SMPlayer consumes approximately 80(-ish)MB and MPV 70 to 75MB the most.

As soon as it goes on to the next track, SMPlayer's memory jumps straight to 520 to 530MB without any logical explanation.

There are times where my whole system becomes unstable due to the excessive memory consumption.

I'm on GNU / Linux Debian testing 64-bit fully updated on a daily basis.

Here are my specs:
