Valve just put out a new Steam Client Beta with some adjustments needed for Steam Play along with Vulkan pipeline dumping and more.

First, they've taken another stab at fixing those pesky zero-byte updates that happen in the Linux Steam Client with Steam Play titles. Something that seemed fixed but wasn't quite there with it sneaking in again in some situations. This is where Steam wants to download a zero-byte update for all your Windows games installed with Steam Play, a pretty big nuisance.

In addition, another Steam Play fix went in to help with missing Proton or data files for Steam Play titles. This should hopefully stop the issue we had recently, where Steam Play didn't want to update with a new Proton version.

For those who use it, Big Picture Mode also now has Steam Play configuration with this update. Perhaps this is a step towards another SteamOS update? Would make sense to have that in.

A Vulkan specific feature went into this beta too, Valve say they have "Enabled Vulkan pipeline dumping and collection if Shader Pre-Caching is enabled".

Steam Input also saw a new feature with "visualization support to the controller HUD and the ability to bind beeps when applying/removing action set layers" along with some bug fixes.
