For me, the Vulcan shader pre-caching is different. It is a pop up with a percentage indicator. This is a regular steam update like it used to be on windows.
I get those popups too at times, but they are not what I am referring to. The shader pre-chaching updates I mentioned work in the same way you described your phenomenon, through the regular update menu.
Since I’ve switched to linux, a lot of games have been starting doing shader pre-caching updates regularly. Might be that.
