The expectation (and yes, cmd mode panels kinda break this) is that you can translate between time and vblank.. so we don't really want the frame count to stop incrementing just because irq's are disabled.. *Maybe* we can do max(hw_frame_count, &phys->vsync_cnt).. we'd have to adjust the vsync_cnt before enabling vsync irq's.. but that seems ugly and fragile/racy.. What will be the value of the hw line count during this window? Is it something we could use to detect that we are in this post-vsync but pre-new-frame period?
