macOS: Editor window cannot be dragged by the title bar, or lags considerably when dragged

[guykayjay]

Godot version

4.0.beta2

System information

macOS 12.6 on M1 Max

Issue description

On macOS 12.6 (Apple silicon), sometimes the editor window isn't draggable, and when it can be dragged, the window lags considerably. It can be resized at the corners and edges no problem - this only affects clicking and dragging the editor by the title bar area and affects all areas of that part of the window equally. I don't know why the window can be dragged sometimes and why it can't other times. This issue is NOT present in 4.0.beta1.

The lagging you see in the video below is not caused by the screen recording - this the actual lag. No other windows are affected by this issue so I have to assume it's a Godot bug.

Steps to reproduce

Open the full editor on macOS 12.6 with Apple silicon and try to drag the window around by the title bar area.

MacOS fullscreen button does nothing in this state. However, if you double-click the title bar the window shrinks and becomes movable.

Is this still reproducible in 4.0 RC 3 or later?

[guykayjay]

@akien-mga Yes, this issue is still reproducible in 4.0.rc3

Can't reproduce. Is the rest of the editor interface lagging as well? As a workaround, you can use default macOS title bar (uncheck Interface -> Expand to title in the Editor Settigns).

The issue still exists in Godot 4.1.1.

When I start dragging either the editor window or game window there's a significant lag. After that lag I can move it around freely. This is me doing click -> drag -> click -> drag repeatedly (releasing LMB after each drag):

It's especially painful to have on the game window, because while working with a single display I move it around a lot

Could this perhaps be the same issue as #82675 and a more general editor refresh/update issue on Apple Silicon macs when using Mobile / Forward + (perhaps Metal-backed) renderers? You could try and see if you have the same issues with the editor setting "Update Continuously" enabled, or when using the editor in Compatibility mode, which both fix the update issues for me.

Some updates on this (using M1 Max on MacOS 14.2.1):

• Issue still occurs in 4.2.1 and 4.3r2
• Issue doesn't occur in Project Selection window when starting Godot, only once you're in a project
• Editor Setting "Update Continuously - On" doesn't change the behavior for me
• Editor Setting "Interface -> Expand to title - Off" DOES fix this for me (thanks @bruvzg )
• Moving window around is indeed a bit laggy, but not that big a deal.
