Bug ID: 54145 Summary: Chessbase redraw issue for arrows Product: Wine Version: 8.0-rc1 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: gdiplus Assignee: wine-bugs@winehq.org Reporter: dav75uk@yahoo.co.uk Distribution: ---
Reproduction steps:
Download and open CBReader - https://en.chessbase.com/pages/download (seen with CBReader14)
Open a board, hold alt-left shift to draw a red arrow from g2 to g4 (drag to do that). Now pick up the pawn on g2, and drop somewhere illegal (i.e. not back at g2, g3 or g4). You'll notice the part of the arrow on the g2 square is now missing.
Note that in Chessbase11 this also affects the default to square (so two bits missing); default to square is if you click the piece, it moves to that square as a 'smart move'.
Quite possible the redraw sequence/priorities are a problem.
