Screen stuttering on macOS since 1.15.2

Hi Joel! I have a few questions regarding your issue. First of all, what are your graphics settings? Most importantly, what are Max FPS and VSync set to? Does the issue still happen when you change them?

Also, did you notice this issue in 1.14.4? Perhaps you used Optifine and the stuttering didn't occur there? That might be good to know if Optifine solves that problem.

Graphics settings for Max FPS are 60. VSync is on.

Vsync off results in screen tearing at any frame rate. Vsync must remain on to play the game.

Max FPS at 60, 120 and Unlimited still result in the stuttering, though less noticeable/frequent at Unlimited. However at Unlimited, chunks render so slowly that the game is also not playable.

This was not an issue in 1.14.4. I experienced a VSync issue with 1.14.2 or .3 I believe (can't recall) but 1.14.4 has been running just fine with regards to any visual tearing/stuttering issues for a while both locally and on my server.

I would have been running Optifine for 1.14.4 but I don't recall the issue existing before Optifine came out for that version.

Why has MC-172109 been marked as resolved? I checked MC 154271 which shows screen tearing (Vsync). The issue I documented above in MC-172109 is not the same thing and has not been fixed in 1.14.4.

Thanks for the information.

It's been resolved as "Awaiting Response", and has been reopened by our bot since you replied. I agree it's a bit confusing, but if we don't resolve tickets awaiting response, we'd have loads of zombie tickets laying around not receiving an update from their reporter in years. (Currently more than 4500 tickets are awaiting response since over a year.)

Can you also provide your CPU details and your openGL vendor, OpenGL version and other details about your OpenGL build in the enviroment section of the bug report.

GPU details were already in the Environment section. Added CPU and OpenGL details. (To the best of my knowledge.)

RE: Optifine in 1.15.2
OptfiFine HD G1_pre3 Ultra for 1.15.2 does not help the stuttering issue. If anything, the stuttering is more jarring. Obviously Optifine at this point is not complete for 1.15.2 but since you asked I thought I'd provide the feedback.

I wanted to chime in again to say that the screen stuttering persists through an update to macOS Catalina 10.15.4, as well as removing the "Minecraft" folder from ~Library/Application Support/ and letting Minecraft start from scratch with a brand new, local world.

I see the same frame stuttering on Minecraft Java Edition 1.15.2 as well as Minecraft Java Snapshot 20W15A, regardless of

• Switching graphic settings to the bare minimum.

• Turning resolution up or down.

• Frame rate up or down.

• When the render distance is set to 4 chunks, the stutter continues to render the game unplayable.

I also tested 1.15.2 with the latest preview version of Optifine, 1.15.2_HD_U_G1_pre13, with no change in the results.

That seems very odd. Do older versions, like 1.14.4, work fine on the same system?

I get some frame stuttering / frame slow downs on 1.14.4 on Mac OS Catanina but it's no where near what's happening with 1.15.2 or the 1.16 snapshot(s).

I always thought the small frame blips I would experience was server lag, since basically all of my Minecraft time in 1.14.x was on my server.

I unfortunately can't create the exact circumstances for 1.14.4 play as the last time I played in 1.14.4 my Mac was on High Sierra, and it's now on Catalina.

That's fine - how it worked then isn't really important. What I'm trying to gauge is where the problem is in terms of the game interacting with the system. It is weird that this problem could start occurring after the release of 1.15.2, yet still affect 1.15.2.

Could you record another video, but have the debug frame graphs open (alt+F3)?

Here is a link to an unlisted video posted on my YouTube channel, recorded today, 2020-04-28 with the debug and frame graphs open.

My immediate reaction to that is that you have biome blend set very high, which taxes the system to a very high level too. It's not certain, but the spikes look like they correspond to chunk rendering, which could definitely be caused by that. I'd try reducing it to the default (5x5) or lower and seeing if that makes a difference.

Thanks for the suggestion. I tried reducing the biome blend setting to 3x3 and then to off. Neither had any positive effect on the stuttering issue.

Here is a link to the video recorded with biome blend set to 3x3:[

(I think you linked to the wrong video, that one is the one from before with 9x9 biome blend)

My mistake. You're right, the link was incorrect. Here is the correct link to the video with biome blend set to 3x3. The choppiness remains the same.

@unknown can you check if this still occurs in 1.17.1

@Anthony Cicinelli - Yes, the screen stutter (most visible when looking left and right with your mouse) still occurs in 1.17.1 as well as the latest snapshot, 21W38A. Tested just a few minutes ago in brand new worlds in each version.

YES! This makes the games unplayable! Vanilla, Optifine, Sodium paired with Lithium... happens with each and every one of these! I have an M1 MacBook Air, 8gb of ram, 256gb storage. And yes this almost always happens when moving your mouse, but not when just looking straight ahead.

I just tried 1.18 and 1.18.1 and I'm still having this same issue. I've been avoiding it by playing on my older MacBook Pro, but there's another issue there right now where the game keeps crashing. 

I know I've read somewhere that it might be an issue with java not being fully compatible with macOS, but I can't remember where I saw this. 

So I didn't had this issue on my Macbook Pro (mid-2012) running OS X 10.11.6, but I do have this issue on my MacBook Pro (mid-2015) now running macOS 11.4 (I'm thinking about updating to macOS 12.1 soon). I'm not sure what OS version I was on when this issue started. 

Experiencing this issue since 2018, my 15 inch MacBook Pro from 2018 macOS Monterey (i7 2.6 HHz, 16Gb Ram & Radeon Pro 560x)

I just tried 1.18.2 The issue still persist, I have wipe my computer once, removed Minecraft and even tried most of the previous release of Minecraft.

Using my work MacBook Pro from 2019 macOS Monterey (i9, 32GB Ram) There is no visual staggering and it works just fine. I hope this can help.

Are you still experiencing this issue on the newest version?
If so, could you tell us your specs and in what cases you are experiencing the stutters?
