VM freezes when scrolling on macOS

[chaos215bar2]

I'm running UTM 4.2.5 on macOS 13.3.1, with the guest VM running the same version of macOS. The VM freezes instantly any time I try to scroll, even on the login screen.

The issue has been present since (at least) v4.1.x. In v4.1.x, the VM would hang and then become responsive again after a few seconds when I tried to scroll with the mouse. I updated my app to v4.2.5 today, and now the VM hangs and does not become responsive again unless I halt and restart it.

@chaos215bar2, as a workaround until this is fixed, I've found that clicking and dragging on scroll bars does not cause the VM to crash.

Any update about this issue ?

Seems to be working for me with MacOS Sonoma (using a trackpad but with the "Use Trackpad" option disabled in the system settings). I think that the older versions of MacOS still don't work, though.

I'm seeing the same freezes running Ventura (13.0) in 4.4.5, irrespective of the trackpad/generic mouse setting.

I'm also seeing these freezes using UTM 4.4.5 on Sonoma (14.4) with a VM running macOS Monterey (12.6)

Same issue. For me, the freezes are particularly bad if I scroll in VSCode, but rarely occur if I scroll in Firefox.

UTM Version 4.4.5 (94):
Virtualisation of Ubuntu 22.04.4 randomly freezes on apple silicon M1.
It freezes about 10 times in a day:(

I tried different versions of Ubuntu (18.04, 20.04 and 22.04) and it freezes on all of them on M1 mac. Any thoughts on how to fix this will be very helpful.

Tried ubuntu 20, 22, and 33. All of them freezing. Tried Fedora 39, no freezing. Firefox eats all memory on Fedora 39 though, and freeze the vm for maybe a minute before crashing X, but Brave browser works fine.

Same issue on M2 mac mini on Sequoia. At least 10x a day.

same happened to my M1 pro, driving me nuts as well ; (

Seeing this on an M1 macbook pro in a 15.1 VM. Sufficient memory is allocated. Periodic freezing on scrolling then it comes back after a couple seconds.

UTM4.5.10,Host Sequoia 15.2, Guest Sequoia 15.1.1, apple backend
Same issue. Scroll on iterm pane slowly will 100% trigger the freeze. I can login to VM use ssh while freezing. Find process WindowServer's cpu usage reach above 100% on vm ( I think this is why vm freeze ).
I find a way to workaround the freeze . Turn off the vm. In UTM, edit the VM settings. On VM setting pane, choose Virtualization, there are Keyboard,Pointer option on right side. Change the Pointer option from "Mac trackpad(macOS 13+) " to "Generic Mouse". After that, turn on vm. There is no freeze any more.
