If qemu window is open back to normal size, keyboard is back to normal, e= verything is back to normal and stable, this behavior i have been testing s= ince several months of qemu releases, i am reporting a bit late here, not b= reaking but it seems important and everytime i accidently minimize qemu, i = remember it later and take qemu window to normal size back always, i try ne= ver minimize it anymore. This problem does not occur if using -display none Guest OS doesn't matter for this behavior, result is always same I am using: qemu 5.1.0.0 qemu-system-x86_64w.exe Windows 10 build 2004 4K screen dpi scaling set to 150% If requested, i can record a video to see the problem clearly, but i think all information i give already clear now.
