Why is UE5 lagging too much whenever I resize a panel?

Basically I just downloaded Unreal Engine 5 to test it out but I noticed that whenever I resize a panel (eg Details) the editor framerate drops to 10 - 20 and I don’t know why as in the UE4 editor this doesn’t happen

BTW, low framerates only happen when I resize the panels (so isn’t really a problem with my PC specs), but if you want to know my specs:

  • GTX 1660 Super
  • Ryzen 5 3600

This is what happens
