It seems that commit 01f05940a9a75e11a2be64993c44ad8dd06e6e26 introduced an issue impacting wlroots and Weston (possibly others) on QEMU with the virtio card. happens on QEMU, and it happens in virt-manager when I do NOT enable GL. (When GL is ENABLED it seems to be fine oddly) It introduces odd flickering, Weston's desktop shell flashes when a new window opens, wlroots also acts odd. This is QEMU 8.0.4 I have narrowed it down to 01f05940a9a75e11a2be64993c44ad8dd06e6e26. Reverting the commit (it still reverts cleanly), and the flicking goes away on a rebuild and this is on Linux 6.6.
