Godot: Godot Editor Drag and Drop Lag on MacOS

[Mootook]

Godot version:
3.2.1

OS/device including version:
macOS Catalina v10.15.5
3GHz 6-Core Intel Core i5
32gb DDR4
Intel UHD Graphics 630 1536 MB

Issue description:
Recently converted my work station over to mac from windows. Setup my Godot project and noticed that dragging and dropping assets from the file system to the inspector panel lags.
I've noticed no other performance hits while using the editor, and this was not a problem on my windows machine. Seems to happen specifically with dragging and dropping images into texture slots in the inspector.

Steps to reproduce:
Drag and drop an image from the file system panel to an appropriate outlet in the inspector tab.

Not sure if it's visible in this gif -- but you can at least notice the icon alongside the cursor dragging along.

@Mootook, can I ask you to check if you can also reproduce #17584 on your Mac?

It looks normal

I'm having what looks like the same issue. For me the lag is extreme, and in the lagging areas the cursor does not move nearly as far as usual for the same mouse movement (it's not just a delayed movement). Some additional notes that may be helpful:

• I've only experienced the issue when my external monitor is connected.
• The lag happens anywhere where the "illegal action" symbol is visible, in other words when you cannot drop the thing in that area. No lag dragging a png into the scene, or a script onto a script slot.

I'm using Godot 3.2.2 stable, on macOS Mojave.

@hmans Wow, super late response....sorry about that. But no, in general the editor for me is rather responsive except in this instance. Also, I've seen mention of monitors in related issues--not sure if it's relevant, but I'm on a Mac Mini Usb-c to an LG 4k display.
