    Hello everybody.

    Yesterday I upgraded Parallels Desktop Business Edition from v. 17.1.4-51567 to v. 18.0.0-53049.
    After that, when I run my VM based on Windows 10, x64, I started to have some issues when scrolling the content inside windows.

    The scrolling is no longer fluent. I can see a kind of horizontal band, about at the center of the screen, where the content scrolls intermittently/overlapping, with an annoying "wave" effect.

    The problem is particularly evident with Chrome, scrolling the content of a page (especially with many graphic elements), but I can also observe it on other applications, including text/code editors (the effect, here, is less annoying, but is still there).

    Before submitting this issue to PD Support, I would like to ask if anyone else have the same issue.

    Thank you.

    While I didn't have the UI performance issue while using Edge, I experienced noticeably more micro-shuttering in Diablo Immortal after upgrading.

    Hi there,
    I'm having similar graphical issues on Windows 11 x64 with the new Parallels Desktop 18 too.
    It feels like the graphics stutter a lot. As you mentioned, it happens in many applications. One of my most used app is for editing CT images, and it's almost unusable now because of the graphics stuttering. Tried this article about performance optimization (https://kb.parallels.com/112091), not helpful at all. So I rolled back to Parallels Desktop 17 and everything went back to normal.
    May I know which Mac model are you using right now? I'm using a Mac mini (2018, Intel i7, 32GB RAM), and I'm thinking it could be related to Intel machines as they have emphasized that Parallels Desktop 18 has been optimized for Apple Silicon Macs.

    I can confirm the same problem. I replied yesterday but the message didn't went through which was bizarre. But anyway, yea the issue resolved when I rolled back to PD 17.

    Ahh now I'm more inclined to believe that it's related to Intel Macs. The graphics hardware of your MBP is very good, there's absolute no reason to have this bad performance with PD 18 then. Hopefully they can fix it soon with a 18.0.1 update!

    Same issue. Had been working fine, but as soon as v18 was installed, when scrolling, UI bugs out.

    Just installed v. 18.0.1 (53056).
    After some minutes of using my VM, I think it is slightly improved, but there are still some obvious problems scrolling windows content.
    For sure it remains worse than v. 17

    So, here I am.
    After a couple of hours using it, I found v. 18.0.2 (53077) more stable. Performance for UI/scrolling are more than acceptable.
    I don't know how much they worked on this issue, but reading the Parallels Desktop 18 for Mac updates summary you can find this: "Fixed various graphics issues with Windows desktop and application". It seems to me they done it.
