Created attachment 1239139 [details] Screenshot showing mild graphical corruption Description of problem: Mild graphical corruption is seen when moving the mouse cursor, dragging windows or when redrawing sometimes. Version-Release number of selected component (if applicable): Using virtio-win-0.1.126.iso How reproducible: Always when KVM scales the guest screen to a high-DPI screen, eg on my Dell XPS 15 with 3840x2160. Steps to Reproduce: 1. Install Windows 10 2. Install qxldod from virtio-win-0.1.126.iso 3. Move mouse cursor, drag windows Actual results: Mild graphical corruption seen Expected results: No graphical corruption Additional info: Screenshot attached showing some corruption around 'operation' from moving the mouse cursor. Most likely, this is an off-by-one or rounding issue.
