Core: Memory leak in v1.0 (Regression)

Is there an existing issue for this?

• I have searched the existing issues

Problem description

I'm experiencing quite a memory leak in FreeCAD v1.0 on a fully updated Win10 22H2 machine with 16GB of RAM, a 12-core processor and 4K monitor. The UI freezes after a few interactions with the menu/functions and a runaway memory leak of 6-15 MB/s and 5% CPU load can be observed in Task Manager next to "FreeCAD main executable". The app throws no error codes and has to be killed.

The memory leak happens even without opening/working on a model; it is enough to play with the menu or Preferences for a few seconds after launch to trigger it.

I'm observing no memory leaks in v0.21, which runs perfectly smooth on the same machine.

I've tried:

• various Win compatibility modes
• restarting in safe mode
• newest weekly build
• newest Python

Any help would be appreciated. Thank you.
