Booted this am and all of a sudden Parallels Tools updates, now when restarting windows 10 guest the display is magnified 300% and no matter what I change the display redraw is incredibly slow and basically unusable. This is atrocious. Anyone else experiencing this? Parallels - PLEASE advise asap. Many thanks
Please try uninstalling and reinstalling Parallels Tools and keep us posted whether it resolves the issue.
