Steam Link

Steam Link

Black Screen ONLY when accessing menu
New PC, Steam working fine, Steam Link works fine except for one issue.
When in the main page, accessing the sidebar menu in Big Picture mode that slides out from the left, the screen goes black.
Backing out of the menu, screen comes back on, you can see the sidebar for a split second as it collapses. Accessing any deeper menus such as the power options brings everything back.
Can stream fine, and it's easy enough to access the menu items I need by "feel", it's just an annoying quirk I'd like it to stop.
OS is Linux Mint 22, Steam and Link both up to date.
