Fusion keeps losing trackpad rotate on M1 MacBook Pro.

[edgemarston]

I recently switched to an M1 MBP. Fusion mostly works well, but I'm experiencing one big bug. Every time the display sleeps, Fusion loses trackpad support for two-finger rotate. It's not a total loss of trackpad input, because I can still zoom in/out... just no rotate.

I've tried opening/closing designs, entering/exiting sketches, and everything else I can think of. Only a full Fusion quit/relaunch fixes it.

This is a pretty disruptive bug for workflow. Any ideas?

Thanks for letting us know. This is an old bug that is hard to reproduce in test machines. 

What is happening is the trackpad drivers are crashing and without restarting Fusion there's no way to get them going again. 

Could you please collect log files the next time this happens. They might show some activity around the sleep event that can give a clue. I'll add this report to the existing ticket for this problem.

Workaround:

Close Fusion before your machine is put to sleep. Starting Fusion only takes about 30 seconds on an M1 machine.

Sorry for the inconvenience.

@Phil.E thanks for the quick reply! I've collected the log files and will PM them to you. Good to hear the issue is on Autodesk's radar.

I am curious, is there a reason it's harder to get trackpad drivers to work correctly in Fusion compared to other software? I haven't experienced this issue with anything else I'm running.

[Phil.E]

Fusion uses it's own trackpad drivers. The native mac trackpad drivers do not provide the ability to give you the experience you have when Fusion is working properly.

There's always native trackpad from the Fusion appstore. This will give you the native mac trackpad experience.

This problem still exist on my M1 Macbook Air (Big Sur Version 11.5.1), any thought?

[george.hartt]

Same for me, any updates? Though this is on a 2015 Mac Book Pro 15", using Big Sur

[george.hartt]

Update: What worked for me was disabling Smart Zoom and Rotate in Trackpad preferences -- then disable and reenable "Use gesture-based view navigation" in Fusion360

I have the same Issue, MacBookPro 2015 Big Sure 11.6 and Fusion 360 2.0.11186.
After my Laptop went to sleep, the only solution is: Restart my Laptop en Fusion 360.
All other suggested "solutions" won't work!!!
This is a real problem to investigate.

Best regards,

I have same problem don't you. have any solution still

[FrodoLoggins]

As I've mentioned before:

1: Exiting Fusion doesn't always fix this.

2: Sometimes the bug gets resolved just waiting/doing something random (without closing Fusion).

Any reason Fusion is the only program I have this issue with?

[edgemarston]

Autodesk, this is really getting outrageous. It's been 8 months. This isn't a weird corner case bug. This is "Mouse support isn't working". That's basic, core functionality.

What is going on?

[FrodoLoggins]

Oh it's been more than 8 months lol. This isn't the first time this has been reported.

Happening to me on a new M1 MacBook Pro. I'd love to hear more about why Fusion 360 needs its own trackpad driver. Knowing a little bit about the underlying systems involved, the juice here doesn't seem worth the squeeze.

[dick.vlasblom]

Well the solution is, in my case, very simple!
If you have a design open it and look at your timeline....
Just click on a feature and say I want to edit it!
Just close it and you will be back on track!
To Python or not, That's THE Question:):)

[FrodoLoggins]

So now that "Fusion 360 is officially supported on macOS Monterey" after the new update, this bug has been fixed, right?

[dick.vlasblom]

Yes, no issues with Fusion 360 and macOS Monterey regarding this topic for me anymore!

[FrodoLoggins]

Glad for you. Still happens to me at least once a day.

[dick.vlasblom]

Ok, just for your information I tested it again the last 48 hours.
MacbookPro mid2015 ; OSX Monterey and the latest Fusion360 download.
Opened a model and kept Fusion 360 open with:
Laptop on accu, laptop charging and Internet connection on and off during the test.
Trackpad rotate function is still working perfect.

[FrodoLoggins]

Glad for you. Still happens to me at least once a day.

@Phil.E Are we gonna fix this bug or what?

[edgemarston]

@keqingsong I would really like an answer on this. At least, can you explain why Fusion is more or less alone among paid professional software in not having basic trackpad driver functionality working properly? This is really embarrassing, and Autodesk has been ignoring it for way too long.
