For this we need to know which bugs are still valid and which could be closed already. Thus we are setting the bug state to "Incomplete" now. If the bug has already been fixed in the latest upstream version of QEMU, then please close this ticket as "Fix released". If it is not fixed yet and you think that this bug report here is still valid, then you have two options: 1) If you already have an account on gitlab.com, please open a new ticket for this problem in our new tracker here: https://gitlab.com/qemu-project/qemu/-/issues and then close this ticket here on Launchpad (or let it expire auto- matically after 60 days). Please mention the URL of this bug ticket on Launchpad in the new ticket on GitLab. 2) If you don't have an account on gitlab.com and don't intend to get one, but still would like to keep this ticket opened, then please switch the state back to "New" or "Confirmed" within the next 60 days (other- wise it will get closed as "Expired"). We will then eventually migrate the ticket automatically to the new system (but you won't be the reporter of the bug in the new system and thus you won't get notified on changes anymore). Thank you and sorry for the inconvenience. ** Changed in: qemu Status: New =3D> Incomplete -- = You received this bug notification because you are a member of qemu- devel-ml, which is subscribed to QEMU. https://bugs.launchpad.net/bugs/1907061 Title: qemu-system-x86_64 minimizing window causes keyboard input lag globally Status in QEMU: Incomplete Bug description: After qemu window is minimized, it causes keyboard lag on the host for al= l applications, pressed keys will be delayed and very laggy, typing to note= pad or any other text extremely slowly appear on the screen, queue is slowl= y processed. 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. Thanks for making quality software, hope all bugs fixed To manage notifications about this bug go to: https://bugs.launchpad.net/qemu/+bug/1907061/+subscriptions
