--- Comment #2 from Nachanon Vetjasit Nachanon_Vetjasit@hotmail.com --- Created attachment 51181 --> https://bugs.winehq.org/attachment.cgi?id=51181 Trace log from Microsoft Paint under WINE 1.7.39
This bug still exists under current WINE 1.7.39, and symptoms are apparently the same (rounded-corner stroke, including an unwanted knot at top-left corner of the rectangle).
The attached file (mspaint-wine1.7.39.log.bz2) is a trace log from Microsoft Paint:
WINEDEBUG=trace+accel,trace+animate,trace+bitmap,trace+clipping,trace+quartz,trace+palette,trace+msimg32,trace+graphics,trace+ddraw,trace+xrender,trace+gdi,trace+gdiplus,trace+bitblt wine mspaint.exe
In this experiment, blue-colored line [rgb(0,128,255) #0080FF] with 11px thickness was used. The rectangle was created by holding mouse button at top-left corner, and drag in south-east direction then release the button.
Note: I found that if I started the rectangle from bottom-right corner (instead of top-left), the unwanted knot will appear at bottom-right corner instead of top-left corner too.
