Moving mouse during "Simulate" appears to half/third frame rate.

As shown below. Completely default scene. Running on 5.4.2.

May be related, but clicking onto the Output Log tab (in or out of simulate mode) causes a long editor freeze (10+ seconds).

Simulate mode while Output Log is shown:

Hate to bump, but this is still happening. It seems to happen in any UE5.4 projects, and I can’t determine why.

Literally a 2/3rds drop in performance when moving the mouse while simulating in the editor viewport, and this isn’t only on my hardware, one of our team is experiencing the same thing.

Any ideas on what might be causing this?

I’ve heard about the Output Log having issues with special peripherals/graphics tablets being connected, but I don’t have anything like that.

My mouse is a Logitech MX Master 3S.
