Mouse button input events not picked up consistently on macOS. Mono version

I am encountering this issue on mac OS Monterey 12.0.1. Godot version is 3.4 stable mono.
Device is mac mini i3 2018, with UHD 630 GPU.

Bug occurs sporadically, 1 out of 10 times when I start the game the bug will occur.
When it occurs, its immediately obvious as my game starting UI elements (buttons) are also affected.

The Bug I would describe most simply as follows:

• one normal left mouse click seems to be ignored/missed, one needs to double click and this is then registered as one normal click

GLES2/3 options are affected equally, and its not specific to one control type (e.g. Button) but seems to affect all controls equally.

Bug seems to go away after some time (window switching and window minimizing/ maximizing maybe helps).

If I understood correctly, this bug should have been solved in 3.4 but for me its still there. Could it be that only Mono version is still affected ?

P.S EDIT:
I just noticed one curiosity which might help someone.

I have a sort of scenario editor at game beginning, an ItemList where one can select one scenarioName string.

When starting the game where there is NO bug, the first item in the list is automatically selected/focused.
When starting the game where the bug IS present, the first item in the list is NOT selected/focused.

No, as the input handling code is exactly the same between non-Mono and Mono versions.

when I start the game

Starting project from the editor, from terminal or starting the exported app?

When the bug happens, are window title text and close, minimize and full-screen buttons normal (bright text and colored buttons) or gray?

I start mine from the terminal, always. It happens both in the editor and in my launched game. 3.4 Mono, macOS Monterey 12.0.1.

It's very sporadic.

Starting project from the editor, from terminal or starting the exported app?

I just made some tests (around 30 starts) and I only got the bug when started via Terminal/ VisualStudioCode F5.
Here is my launch.json:

    "version": "0.2.0",
    "configurations": [
        {
            "name": "DebugTerminal",
            "type": "godot-mono",
            "request": "launch",
            "mode": "executable",
            "executable": "/Applications/Godot_mono.app/Contents/MacOS/Godot", 
            "executableArguments": [
                "--path",
                "${workspaceRoot}"
            ]
        },

But it could be just small test sample.

Yes, I just noticed that when the bug appears these buttons are gray.

Don't know if related, but when I try to click to focus the Godot editor window on macOS (MacBook Pro M1 Max, Monterey 12.0.1) there's a delay of at least 1 or 2 seconds before it actually gets focused, very annoying.

It seems to be dependant on how complex the scene in the window I'm focusing is, with a simple running game I get less delay, but still noticeable if I try to drag the window at the same time.
I'm starting Godot normally, not from the terminal.

When I alt+tab to set the focused window (instead of clicking) I get less delay, but it's still there.

• Can you reproduce this if you enable Update Continuously in the Editor Settings?
• Can you reproduce this if you set Unfocused Low Processor Mode Sleep Usec to 6900 in the Editor settings (while Update Continuously is disabled)?

Ok, either way the issue doesn't appear anymore, or it's quite mitigated.

Well that's interesting. I always launch godot from a terminal (godot-mono -e .) in order to see output logs. If I launch it from spotlight and open my project from there, I couldn't reproduce the issue when I tried closing and re-opening godot 5 times.

Oh I'm sorry, I was responding to the original issue, not this alt-tab issue. I'll delete my comments.

* Can you reproduce this if you enable **Update Continuously** in the Editor Settings?

* Can you reproduce this if you set **Unfocused Low Processor Mode Sleep Usec** to `6900` in the Editor settings (while **Update Continuously** is disabled) ?

I also tried these 2 tips and they don't prevent the problem.

The bug I can spot upon starting my game by looking at the window icons:

If these 3 icons are greyed out (like in the screenshoot) it means left click mouse input will fail to be detected.

Interestingly, I could NOT get this bug to appear when starting the game directly from Godot editor.
Also, starting the game from godot editor and THEN starting it from terminal/VSC F5 seems to mitigate the problem.

So the bug appears most often when you dont start the game from editor at all.
