App is crashing daily due to memory usage

[turt2live]

Steps to reproduce

I am making assumptions about the cause here, but here is the pattern for me:

1. Have a relatively large account
2. Use that account a lot throughout the day (lots of encrypted rooms)
3. Immediately after changing rooms, client crashes randomly (blank screen); Memory usage drops to basically nothing.
4. Quit the app from the task tray
5. Reopen app, and repeat.

Outcome

What did you expect?

Not crashing.

What happened instead?

Blank screen after 6-8 hours of using the app. Sometimes as few as 2-4 hours. Appears to be related to how many rooms I click through to read messages in. Most of those rooms (90%) are encrypted with plenty of devices, however I only speak in about a dozen of them.

I'm in 3678 rooms (3399 visible) as of writing.

Unfortunately, getting a memory profile is difficult because the act of doing so often pushes the VM over the limit and crashes due to OOM. By the time I can get a profile after startup, the process is dangerously close to crashing while it tries to interpret the profile it just took.

The memory behaviour is a relatively steep cliff at startup: the OS reports Element using 2.6gb with only 60 seconds of uptime, but it still takes several hours for it to finally fill the gap to the point where it can crash due to memory pressure. Meanwhile, it takes 15-20 minutes for my CPU fan to stop spinning after startup, which I believe is the "decrypt all the rooms" loop running.
