When I open another unreal asset window on my computer, there is a phenomenon that the frame drops sharply.

I’m using two monitors.
The Unreal Engine is open on the main monitor,
A single Unreal Asset window is open on the sub-monitor.

Just by opening an asset window on the sub-monitor,
The frame of the Unreal Engine viewport on the main monitor drops sharply.

Is there a solution to this?

I have the same behavior in all Unreal version tried so far, from 4.27 all the way up to 5.2.
