Created attachment 153262 [details] Screenshot of Windows10 pointer preferences under Virtualbox I am using Plasma 5.26.0 with a 4k screen and 200% scaling. The scaling of XWayland apps work well now, thanks! One problem I still have is with Virtualbox, with a Windows 10 guest and mouse integration. The Windows10 pointer is twice too big. I don't have this problem with KDE/X11 or Gnome/Wayland, so I reckon it is a KDE/Wayland bug. STEPS TO REPRODUCE 1. Use Plasma 5.26.0 with a 4k screen and 200% scaling 2. Launch Virtualbox with a Windows10 guest and mouse integration 3. Look at the size of the pointer OBSERVED RESULT The pointer is twice too big. EXPECTED RESULT The pointer should have a normal size.
