Symptoms

Since the SWAT update (v0.31), playing missions causes the game to slowly use more and more RAM (even when the game is paused to the menu or in the results screen). In ~20 minutes, it can go up to 2.6 GB of RAM of usage, and I've seen it run away up to 8 GB before I killed it. Previous to this update, it never seemed to ever go over 1 GB of RAM throughout long play sessions.

Reproduction

1. Use any version of Proton, I'm using Experimental here (newer than 7.0-2, doesn't seem to matter though tried several, even the unofficial latest GE Proton release 7-20)
2. Start a program analogous to Task Manager (like bpytop or htop) that can track RAM usage of specific processes
3. Start the game, run a mission (any will do, but for the purpose of standardizing let's go with Gate Crasher, the first non-tutorial ranger mission)
4. Complete the mission, then stay in the results (stars) screen for a couple minutes. The RAM usage continues to increase. For reference, a normal value here previous to SWAT update seemed to be ~850megs.
