Works with the M1 Macs, but not completely well

[Ryanfsdf]

Describe the bug | 问题描述
Mos works fairly well with my new M1 MacBook Air. The scrolling becomes much smoother on my 144hz monitor. However, it is not as smooth as on my 16 inch MacBook Pro. The 16 inch MacBook Pro seems noticeably smoother on the same monitor compared to the MacBook Air.

To Reproduce | 如何重现
Install Mos on a new M1 chip Mac.

Expected behavior | 期望结果
Scrolling should be very smooth. It is much smoother than without Mos, but not extremely smooth like on my Intel MacBook.

System Info | 系统信息:

• OS: MacOS 11.0.1
• Browser: Chrome, Safari
• Application: Whole system

My scrolling on the M1 air is definitely consistently less smooth/laggy. Not a good experience atm - but still better than notchy scrolling without Mos.

[wolterkam]

I'm having the same problem here, might this be related to MOS being and Intel app?

Thanks for you guys feedback, but I don't have an M1 device to test now. If someone can try to compile code based on the dev branch on your M1 device, can you help test whether the laggy is caused by the compilation environment or the code itself?

I just tried building and running both the master and dev branches on my M1 MacBook and it exhibits the same behaviour as the release build (3.1.0), so I'm inclined to believe that the issue is with the code itself.

@Ryanfsdf OKay thanks，i'll figure out why

hi, I am new Mac user, I try to install MOS on big sure m1 MacBook Air and can't do it because it told me that apple don't know if it safe, please, can someone help me to install?) Thanks

Try opening it again. Then open Apple menu -> system preferences -> security -> general tab. You will see a wordy warning with "Open anyway" button, click it.

great, Thank You
Must tell on m1 it works incorrectlyy - scroll speed in browser is ok but in photoshop very-very fast, unreal to work, need set all to minimum but then scroll in browser is toooo slow

You can set different speeds for different apps. The problem with Photoshop is most likely Adobe's fault, not the M1's fault.

For those of us who can't compile, is it possible that you publish temporary universal (or Apple Silicon) DMG? Thanks!

[ArttuLai]

Maybe I'm just don't see the difference when I don't have my Intel-Mac anymore to compare with, but I don't see any big problem with MOS on my M1 Air. I'd like to test an M1 binary also.

Here is a dev build for Apple Silicon:

Thaks! But there is a bugs in Sublime Text. Cursor always works like with Shift key pressed🧐

Thank you. I tried it on MacBook Air M1 for about a day, and found a weird problem. Sometimes my clicks on context menus did not register. F.e. I right-click and image and try to "Copy image". The menu closes but nothing happens (image is not copied). Same with other menu items. Uninstalling Mos resolved the problem. Hmm! Ready to help if I can.

[ArttuLai]

@vladstudio Okay so that's what it is! I have been wondering if it's the Big Sur betas or something that's causing the click-through bug, I’ve been experiencing it occasionally too. Quitting the affected app and re-opening solves it — until it happens again.

[Maxung]

Yeah, sadly I had the same problem so I had to uninstall Mos

Sorry, this is a bug in the development code, it has been fixed, you can compile it right now or wait for my recent release.

Thanks for the fix! will wait for the upcoming release.

[Maxung]

Thanks a lot, if anybody can't wait, here is another universal binary (I will delete it, when an official one is published)

Sorry for the bother, after I restarted my Mac this problem is gone. :)

I noticed an instant improvement on my M1 mini on my 144Hz screen, the update has definitely fixed it for me.

Have you compared with an Intel Mac? I'm comparing side by side with an Intel Mac on the latest update (3.3.2) and the M1 Mac is still noticeably choppier at 144hz.

[Caldis]

@Signynt @Ryanfsdf Mos using CVDisplayLink (also known as Metal) to process and post the scroll event into system. So it will always synchronize with the refresh rate with your display.

I found another issue that occurs on what I suspect are iPad apps that have been ported to Big Sur.
When scrolling on them using smooth scroll it keeps getting 'stuck', especially if you try to change directions or go to fast. I made a video as an example with the new Notability Beta, that is basically the Notability iPad app running on Big Sur. The same thing happens with the app from the appstore 'Flashtex', which I also think is an iPad app.

Can confirm, especially on Twitter for Mac

I add a Scrolling Phase Module since 3.3.0, by simulating the trackpad behavior to fix the issue in chrome or some app stuck in over-scroll, I think its the problem.
maybe you can help to test the 3.1.0 or earlier version will cause this issue ? thanks for your feedback ~

Yes that seems to be it, I don't have the issue using 3.1.0, but with that version the scrolling on all apps is not quite as smooth on M1 as with the latest release.

[Caldis]

@Signynt thanks, seems I need limit this feature to specific apps

[lzap]

Just to inform you guys, I am testing another (commerical) mouse smoothing app and I experience the same sluggish experience. The stuttering is mostly in the beginning of the move, I experience this in Safari.

Also another problem is that my screen does report to run at 60Hz or 75Hz but apparently something is not right with timing of the M1's video output and other users report that as well. Scrolling is definitely not running at full framespeed, this is not a problem of mouse or the app, even dragging windows around is not as smooth as on other OSes. So Apple has to fix this.

All and all, not the greatest experience so far for some users.

is this issue resolved for others? i feel like it is not resolved for me

[kcstagepro]

#333

i bought a 8gb Mac mini about a month ago - was getting a similar lag issue to #333, even though that seems resolved

so i ordered a pair of 16gb mac mini's one for home one for office - same MX vertical mouse - same mac mini same everything but different display

office machine works fine - home has been giving me lag at the start of some scrolls, much like #333

i think this Mos - Fixed Catalyst Scrolling.zip
might have fixed it

I am using v3.1.0, and this issue has never appeared again.
