Hey - just upgraded to the 2.8k 120Hz display, and started noticing significant buggy graphical artifacts immediately.
It looks like evenly distributed horizontal rows of pixels have significantly delayed refresh times. They lag out repeatibly in 2-3second intervals - image attached:
I have a video but can’t upload here - I uploaded it to youtube here
I have updated my OS (ubuntu) and all drivers etc but no avail. The bug occurs on the boot screen also, making me think it’s a hardware issue. I have re-seated all plugs and screws but the issue persists.
Anyone else seeing something like this? I suspect I will need to get a replacement screen
Relevant Details:
OS: Ubuntu 24.04.1 LTS x86_64

Framework Laptop Version: I have the 13inch framework laptop, I believe the 12th generation (not sure how to check, received it feb 2023 though)
Also worth noting that I upgraded from intel to AMD CPU (and thus the ram and wifi chip) over my time owning this laptop.
Also note: I am new to this forum, I gave it a good search prior to posting but couldn’t find anyone else with the same issue (could be skill issue with searching). Thank you for the help!
