I use my UM690 primarily for video editing. Was doing fine until I updated the driver to 23.4, then the program would hang after just a couple of minutes of normal editing. I figured it had something to do with the video, because when I would restart the app, things I had clicked on when the app "hung" had actually happened. Also, while it was locked up, I'd minimize the window, then when restoring it the screen would be blank.
UM690 is a Ryzen 6900HX. I've assigned 4 GB of its 32GB memory to graphics.
After rolling the driver back to 23.3, the hanging stopped.
