--- Comment #3 from C. Leu kle@bluewin.ch --- A new little addition, the described issue still exists also under Wine 6.20.
When a line is drawn in Paint.NET 3.5.11 (and the built-in gdiplus.dll is used) the operation always takes place with a delay.
This is not the case when the native gdiplus.dll is used, - the drawn line is painted 1:1 without any delay. Unfortunately Paint.NET 3.5.11 runs not stable when the native gdiplus.dll is used, - it crashes reproducible after some time.
However, in conjunction with the built-in gdiplus.dll Paint.NET 3.5.11 runs otherwise stable and reliable. It could be said, that Paint.NET 3.5.11 runs apart from this gdiplus.dll delay-issue effectively platinum-like. ;-)
