[RESOLVED] AMD F39 USB-C hiccups with external display directly connected via USB-C

Somewhere along the line I did some more testing. The external display hiccup has gone away. The original work-around was to keep the external monitor at 85% brightness. If I got to 100% brightness, instability was introduced. Now I am able to go to 100% brightness. There is no firmware for the monitor. The only thing is keeping F39 updated. There have been a number of firmware releases and kernel releases since I last visted. I am curious if anybody else is seeing improvement? @jwp?

As I don’t have access to a USB C display (using HDMI and DP via the expansion cards here), it would be worth filing a bug report with Fedora.
