High Utilization/FPS Drop when highlight top toolbar/Content drawer/blueprint opened

Weird issue on Unreal Engine 5, clean install, happens on all 5.3, 5.5 and 5.6 and reproductible. Any idea how to fix this and why it happens ?

if I focus the main viewport, my fps is 120.

If i start to go out, opening the content drawer, highlighting the top toolbar like Edit/File/Window/Tool, opening a blueprint, the fps crash to 10.

Maybe it is because of my computer, not sure if there is any setting I should be aware to disable/enable to remove this issue.

I am using a laptop ASUS ROG Strix Scar 18 with 32go ram, 4080 RTX 12G VRAM, I don’t remember it was happening but since I have installed 5.6 the problem appeared and doesn’t leave even if I downgrade to 5.3(where i used to develop my game there)
