RAM usage increasing, but never decreasing resulting in a crash. #1902

Describe the bug

Ever since I updated to the 2 new updates released yesterday, in the games Half-Life 2 (Source Engine, installed from Steam, Native) and Severed Steel (UE4, installed from GOG, Proton Experimental) when the RAM usage goes to around 11.4 GB, then I press the "STEAM" or "●●●" button it shows the Steam UI but with white squares on the UI then the game crashes then goes blank, or if I wait a few more minutes more.

I noticed that in Severed Steel, when I load into a new level, my RAM usage increases, but it never decreases. Same thing in Half-Life 2 in Highway 17 but when I just navigate the place (since it's an open-world-ish level). And the performance also gets slightly degraded too.

All of this wasn't happening in the last update.

What did you expect to happen?

I excepted to play my games for more than 10 minutes per-session.

Extra information or context

Here's the Proton Log for Severed Steel. I don't know how to generate a log file from Half-Life 2. steam-13380315529424666624.log

Running on a Steam Deck LCD 512 GB model

Tested on both the Stable and Beta Steam branch; exact same result.

I tried running Half-Life 2 with Proton 9.0, same issue, but it happens quicker.

Edit: It seems like my RAM is going into this "buff/cache" thing. I did a quick search online and I found that's meant to be utilized by other apps when needed. But it appears like it's not happening since my games keep on having its RAM usage increased, but never decreased. In the log files of the test that I ran with the game Descenders (Proton 9.0, Unity, installed from Steam), it shows that my RAM hasn't cleared at all ever since running it.

Also, I noticed that in the game, Jusant (Proton 9.0, UE5, installed from Steam) there were loading screens, which weren't there before the update that broke things for me.
