Re: XPS 9380 FHD 13: JPEG-like artifacts on LCD
I'm glad to hear you got the issue resolved by disabling the panel self refresh. I'm surprised that feature is now showing up as it was previously removed via a combination of a BIOS update and an update to the graphics driver as it was causing issues with screen blanking and flickering.
I believe this was connected to any system running the Intel HD620 graphics driver. I'll pass this information back to engineering.
