AutoNoVsync accepts frames as fast as the GPU will take them, so a redraw burst costs whatever the hardware can be made to do rather than one frame. That is the wrong default for a toolkit whose stated goal is to save battery, and it is worse than wrong on this machine: the GPU here is the host's real one reached through virtio-gpu, so frames nobody will see are paid for on somebody's desktop. AutoVsync picks Fifo, which every backend supports. Note this is not an idle drain -- iris only draws when needs_redraw says something changed, and the tabs example guards its stats string -- so this bounds the cost of a burst rather than stopping a spin.
