2019 MacBook Pro 16" Glitching out of nowhere.
When is Apple going to recognize the issue of your extremely vulnerable and delicate flex cable. Please refer to the video. This is a design flaw and the burden should not be placed onto the consumer for this issue.
If you notice in the video provided (you won't let me upload a 1.2mb image - even though your threshold is 5mb) this is a variable display issue most likely due to the extremely delicate flex cables you've hardwired to the entire display. To fix this issue requires a total replacement - and this won't last that long knowing how lightly used and rarely moved this particular MBP is.
It's shame you can't acknowledge the failure and own up to it and make it right for your customers.
