I finally see we went above the 60fps threshold, but the editor itself is now lagging behind 1-2 seconds !
Everything is choppy, not even usable.
Anyone else experiencing this ? I’m using URP.
I am.
Sounds like Unity Issue Tracker - Stuttering Scene view and Game view when in Play mode, a fix is coming. Try enabling vsync in the gameview to mitigate the issue for now.

It happens for me even when not in playmode.
Thanks for the reply. Vsync, doesn’t help, in edit mode is a bit less, but still not usable.
Is this issue M1 Mac specific? A friend with an i7 Mac had similar stutters, worse than usual.
I did get 60-70 FPS while having massive input lag and frame dropping (something like 9/10 frames being dropped, felt like).
Friend had around 7 FPS though, so I think it may have been the memory leak in the other thread?
Been a few weekends now wasted away, mostly fighting Unity issues on one of our ends 
This beta feels much more stable than the previous ones though, this big issue aside.
It is not M1 specific.

Can confirm this issue is happening on an M1 Air, and just to be specific I am not using an external monitor.
Just tried beta14 : Same problem … Absolute misery

Yeah sorry about that :(. It landed a day after beta14 was cut, and it only made it to beta15.

Grrr … Could you possibly put a ‘hotfix’ in the meantime ? Closer to RC betas are taking more time right ? Thank you anyway for fixing; if fixed 
Unfortunately we don’t have any mechanism to do this.
No, they should still be published weekly. I think b15 will come out this week.

I have Editor Flickering on Mac Air m1 (2021.2.0b14). is it the same bug?
It’s a separate bug (https://issuetracker.unity3d.com/issues/game-view-glitches-with-apple-silicon-editor) but a fix is also coming.

I am getting this heavy flickering as well, here’s an example:
What’s the best course of action, downgrade it to a previous beta? Which one would you consider the “most stable” version for M1?
Thank you!
Beta 12 should not have that bug.

B12 is stable-ish; 13 and 14 are broken (for me).

It’s better in B15 now, but still has the lag issue. FPS is showing 60, but on screen it feels like 30-40 fps. In B11, it’s buttery smooth and matches the 60 fps. I’m on an i7 iMac.
