Problem with performance and resolution on external monitor after update

[jedrzej30]

Hi there,
something like a month ago i've bought M1 Pro Mac 14'. Since this time I have parallels desktop and after last update i've got 2 problems:
1. On running windows, while i'm changing resolution from window to full screen parallels won't recognize my screen size (34' 3440x1440) and every time, when I want to work in window or fullscreen I have to change resolution manually. Everything was running smoothly before update.
2. Performance after update is poor, even on Google chrome - its laggy as.. as you know what.
I did not change any settings at after/before update.
