Not able to use *properly* with two instance of Cursor on Ubuntu

Describe the Bug

I’m Not able to use properly with two instance of Cursor.
Each instance with a different project folder.
While one working perfectly, the other instance is very laggish and almost unusble
It feels like there is a limit on the other instance, because anything else working just fine, I can even open Webstorm or another visual code and they work just fine with 1 open instance of cursor, so my guess is that there is osmething in Cursor itself that limit the other instance.

i’m using a pretty good hardware.
i9 14900HX (32 cores)
32 GB memory
RTX 4070
1 tb
(None of the above reach to the max when I having those issues)

Steps to Reproduce

just open two instance, start to work on one, using the agent.
the second one is very laggish.

Expected Behavior

using multiple instances on different project folders (the max I can untill my resources getting to max [CPU/memory…]
