I also get glitching at a VT - often the screen is not updated when typing or running commands. I have to switch the system to another VT and back to get it to update. Created attachment 2007277 [details]
video of the problem
Here's a video of the problem. At the start I flip between "Disable" and "Enable" a couple of times - you can see that the stuff that should appear when clicking "Enable" doesn't really fully appear. Then I type a root password into where the box is (but you can't really see it) - partway through typing, the box appears, but it only shows three characters as typed even when I typed 11. Then I type the same 11 characters into the Confirm: box - partway through doing this, the screen suddenly updates to show all 11 characters in the Root Password box. Then I think I flipped between Enable and Disable again a couple more times. Anyway, it gives you the flavor.
With qemu 8.1.3, running the exact same VM, no problem. I've reproduced this with both a VM created with 8.1.3 installed (where I then subsequently updated to 8.2.0) and a VM created with 8.2.0 installed (which 8.1.3 won't start because its settings are too new).
Can you provide the guest XML - i'm especially curious if this is SPICE or VNC graphics. Created attachment 2007367 [details]
XML of an affected VM
Here. It's just a default libvirt-created VM, as I said, switched from BIOS to UEFI at creation time.
When I created a VM with qemu 8.2 installed I got pc-q35-8.2 instead of pc-q35-8.1 (not sure if there were other changes too), but the bug affected both. Reproduced, this happens when SPICE and virtio-vga are combined at least. Didn't hit with SPICE and cirrus. Filed upstream: https://gitlab.com/qemu-project/qemu/-/issues/2085 Needs this fix

Thanks! x, y, they're so *close*... can we get that backported, then? (In reply to Adam Williamson from comment #8) > Thanks! x, y, they're so *close*... > > can we get that backported, then? We're currently doomed by zlib-ng not providing a -static package, so can't build QEMU. Once that's fixed I can build the patch. The fix for this is now built into rawhide. |
