YEAH! Another blob is gone!

that’s completely unrelated to firmware I suspect, and to the display init since those versions use two different methods

Agreed, the issue is elsewhere, I am just not sure where. I stole some cycles for this just now and all my searches/reading online yields nothing. Either I am using the wrong search terms or this is a rare enough setting that we are the first ones hitting it. Do you have any ideas or pointers to where I could dig further?

As I only have access to my “problem monitor” with occasional blanking until Friday next week I would love to take 4.11-Purism-1 for a spin to see if it resolves the issues. Although unrelated, it seems that 4.9-Purism-2 has improved overall system stability as I have not had a single crash for more than two weeks.
