Comment 10 for bug 2056445

> this system has a single DIMM which was provided by framework: DDR5-5600 - 32GB (1 x 32GB)

My system is 8GB, single stick, same speed 5600 MT/s, same company (A-DATA).

> Restarting firefox temporarily resolves the issue. This behavior started to happen after I switched to X11.

You're the first I've ever heard of this. Hopefully it's not present in Wayland. There is very little testing or development that happens in X11.

> After setting UMA_Game_Optimized, I can confirm that (after 30 minutes of usage), the system appears far more stable.

That's good to hear the workarounds improve things for you too.
