I am one of the users in question from the linked issue. Nothing new on my end, other than that it is an odd one where the amount of blanking is very much dependent on the display resolution and I think also somewhat on the CPU load. I should be able to give some more feedback in a few weeks when I can try out a range of different monitors. With my current setup this is not that big of a problem as the blanking with 2560x1440@30Hz is perhaps once an hour or so.
