I did a last test before giving up with
<latency>
<delay>0</delay>
<refresh resolution="1080">
<min>23</min>
<rate>23.976</rate>
<max>25</max>
<delay>167</delay>
</refresh>
<refresh resolution="2160">
<min>23</min>
<rate>23.976</rate>
<max>24</max>
<delay>167</delay>
</refresh>
</latency>
and nothing new happened obviously. 2160 is still OK and 1080 still delayed. I also tried without the default <delay>0</delay>
setting without any improvement.
I’m giving up on testing for now, until something new comes up
I’m back on 20241129 for day-to-day use.
