Intermittent trackpad scrolling lag in macOS VM on Parallels

Hello,
I am currently evaluating Parallels Desktop Pro on my MacBook during the trial period, and I have also received the 50% off offer. I am interested in purchasing it, but I need help with an issue that directly affects whether I can use the product reliably.
My setup is a MacBook running a macOS virtual machine in Parallels. The main issue is intermittent trackpad scrolling lag inside the macOS VM. Sometimes two-finger scrolling works perfectly, but quite often the scroll input is ignored or arrives with a delay. In some cases, the VM follows the scroll movement about a second later, almost as if the input events are queued and delivered late.
I have not found a consistent trigger, so I cannot reproduce it on demand, but it happens often enough to affect normal use. The host Mac itself does not have this scrolling issue.
I would like to know:
1. Is this a known issue with macOS VMs on Apple Silicon?
2. Are there recommended settings or workarounds for trackpad scrolling/input delay in a macOS guest?
3. Is this something Parallels can fix, or is it currently limited by Apple's Virtualization framework?
4. Would a technical report help your engineering/support team investigate it?
This is important for me because the main reason I am evaluating Parallels Desktop Pro is to run a macOS VM reliably. I would like to resolve or at least clearly understand this issue before purchasing.
