Started about a month ago on my personal desktop. Sometimes when I leave my PC alone for a bit (at least when it seems to happen). Even happens on the login screen. I basically have to restart from the power button to get out of it. Even happens on the login screen.
Windows is kept up to date (OS Build 19045.3693), and specs are here. CPU is getting a bit old (i7-8700k)
I've tried running Karhu memtest and furmark to check RAM and GPU and they seem fine. I've run prime95 and it seems one thread consistently fails. It may be my CPU as I have overclocked a bit in the past but kept nothing that would give prime95 errors and it has a decent AIO on it. Windows event logs doesn't give anything in particular (those COM Server application warnings, and an Error when I force restart but that's everything notable, and the Warnings happen even when it doesn't freeze).
I'm guessing it's my CPU but anyone have any other troubleshooting tips? Thanks!
There exists different sizes for QR codes for more data but I think most devices just read the standard size. I'm not sure how resolution is handled
