Public bug reported:
Since the 24.04 upgrade, my external monitor is blincking frequently. I did not
discover the actual cause but it is linked with interactions in applications
running on the internal screen of my laptop (HP Victus 16).
Seems I am not the only one ...

It is not comfortable for the eyesto have this behaviour. And it's very
irritating!
