Valve has released a new Steam Client update that fixes an issue where Vulkan-based games would hang after users switched windows. The update also enhances security by including a new certificate revocation list.
Why it matters
The security component is critical, as updating revoked certificates prevents attackers from using compromised private keys to impersonate legitimate web services.
The update mitigates security risks associated with 8 compromised TLS certificates originally identified by eMudhra. This patch specifically targets the stability of Vulkan-based software following an alt-tab user action.
