Gdiplus Pen constructor change of behaviour in Windows 10 KB5006670 update
When creating a Gdiplus Pen for a hair line we have always used 0.0 as witdh argument for the Pen constructor. With the KB5006670 this no longer works - the constructor changes the width from 0.0 to 1.0 (the default) and the width scales with various transformations - which is not what a hair line should do.
Explicitly setting the width (post construction) to 0 still works.
Is this a bug that will be fixed?

2021-10-14T01:38:51.693+00:00 KB5006670 release health does have a Microsoft Graphics Component update but It‘s probably not a bug. And It’s preferred to specify constructor parameter(s) directly instead of depending on default behavior.
