Graphical corruption on Legion Go and other issues.

I recently reinstalled Windows 11 and Bazzite from scratch on my Legion Go, and appear to be running the latest version of both. While Win11 is performing as expected, I'm having issues with Bazzite. In both games and the Steam interface, I get graphical corruption similar to what's seen on the Raw Fury tab in the attached photo. I also seem to have lost the HHD functionality. And Decky interface. The controller button to bring those up is doing nothing, though it works in Win11. I recall seeing a crash a day or two ago and choosing to disable Decky until "the next boot" but it never returned. I think I lost the HHD interface at the same time. And the Desktop interface does not show the taskbar. I'm betting the desktop issues are related to doing the installation while attached to a USB-C dock with external monitors. Any thoughts on how to fix any of these issues would be greatly appreciated.
