Scroll lag with MacOS Tahoe 26.5

Hello,

I'm on a Mbp M5 pro with Tahoe 26.5 as host and same OS as guest.
Noticing intermittent lag when scrolling with trackpad, for ezample within the Brave browser. Sometimes it freezes the entire vm for seconds.
Using trial version of Parallels.

Before this, I tested UTM and had similar issue, but with Ms Teams and other Electron apps, not with Brave, and lag wasn't so pronounced (didn't last seconds).

 

some update: in UTM scroll lag can be fixed by changing the pointer option to "generic mouse" in Virtualization options.
Not sure if same is possible in Parallels, I don't see any setting for this...

 

I using i5 with 128 GB of Ram, windows no longer operates correctly after update 26.5, windows appears transparent and some text stack on top of each other. When opening edge and going to copilot on the side it opens and closes a lot. Using cmd and unable to enter any commands.
