Odd issue - high memory use crash

[BMGD 0]

I'm using Win 11 on Ryzen 7 PC with 32GB of RAM printing via USB on an Ender 5.

When my version of Cura 5.4.0 starts it uses about 140MB of RAM but this climbs quickly getting to 10GB in 2min 43 secs. It reaches 15GB in about 4m30s.

Eventually at about 28GB Firefox tabs start to crash, then the screens go black and about 30 seconds later the print stops as Cura crashes. Forced reboot is the next only option.

Any ideas?

Completely uninstalled Cura 5.4.0 with Revo Uninstaller. Reinstalled and the same issue, RAM use climbs and climbs.

I've noticed this too.  I also encounter how Cura text will look jagged and checked my video drivers.  I have the latest.
