Unity 3d game mode flickering and lagging

Hello, I downloaded Unity 3d with all updates and after I started play mode it will start lagging and flickering screen. It looks like it needs more memory to run it or smth like that. I can’t do anything because it’s to laggy. Maybe someone know how to fix that? I attached the video how it looks.

I use macbook pro 2020 m1, 8gb ram.

Hi,
I’m having the exact same issue and I’m using the same MacBook. I see there isn’t any reply on this post, did you find a fix? if so it would be really helpful if you share.

The same issue.
Unity: 2021.1.25 ( 1.26 also has this issue)
Mac: Mac Mini(M1 8GB) with BigSur 11.3

It’s a bug with recent updates on all versions and is in the works being fixed, I think. I’m not sure if it’s a macOS issue or an M1 graphics issue, but for the time being I’m sticking to version 2021.1.17 since I know it works decent enough. I’m sure picking a few versions ago LTS version would also be decent until things are working properly again.

Is there already a bug report for this as it is very annoying and happening in Unity 2021.1.26 and the latest Beta 2021.2.0b16. Sometimes it flickers so bad the Scene View window just goes blank.

iMac M1 (Rosetta)

Another thread mentioned switching the color space from gamma to linear, and this made my flickering stop entirely.

Unfortunately some of the platforms we use need gamma colour space. But isn’t this player-related as this flickering happens in the editor on the iMac M1.

Does the mentioned version support M1 MacBook Pro? and what’s the compile time on it?? does it work smoothly?
My workflow has been affected due to switching to m1 Macbook Pro.

Thanks, This fixed my problem too!!

Same issue on 3 different Mac Minis with M1 chip. (Rosetta)

Unity 2020.3.21f1

How do you change the color space?

Worked for me, thank’s. Unity Version 2021.1.27f1 (also had some more bugs with newer versions, 27f1 works fine for me now).
Had this problem on the new MacBookPro 2021, so there is still no fix from Apple/Unitys site.

same problem but on an iMac M1 really annoying

FYI just in case this is related:

Same

same issue even with the colour space changed

I reduced the fps to 30 by adding the following algorithm to the main camera.

using UnityEngine;
//Avoid flickering
public class WAntiFlick : MonoBehaviour
{
void Start()
{
QualitySettings.vSyncCount = 0;
Application.targetFrameRate = 30;
}
}

I had this issue after I built my game. It had no issue whenever I play my game in the editor, but it began to flicker after I built the game.
The last time I built the game, it had no issues in screen flickering. It’s just odd it happened just with my recent build.

thank man
