Please describe your issue in as much detail as possible:

All I did is launch the game and launch Deus Ex: Mankind Divided to play some. Instead after about 30 minutes of gameplay, my system ran out of RAM NOT because of the game, but because of the steamwebhelper leaking Gibibytes of RAM (journalctl log with 3 entries attached below)

Steps for reproducing this issue:

Launch Steam.
Wait in the store page (or ANY page because it's all web)
Gain 13Gis RAM usage. Profit.

I've seen this too, i boot up steam and it will eat up all the ram and CPU processing it can get

Ive attached a btop image showing what happens as soon as steam is launched

Ok i seem to have fixed my issues, it was a mix between stale proton versions and having a corrupted prefix at ~/.local/share/Steam/steamapps/compatdata/0/

Updating my proton versions (specifically cachy's proton) and removing the prefix for it to regenerate have fixed my steam memory leak.
