--- Comment #4 from Sebastian Lackner  ---
As Dmitry already pointed out, the check is intentionally written like that.
The purpose is to filter only 'Unhandled blend factor 0' messages. When factor
!= 0, the message is printed more than once.

The patch was added a while ago when I was debugging an application where only
this message was spammed very frequently.
