Summary: Combobox, doublebuffering is not working correctly Product: Wine Version: 1.3.23 Platform: x86 URL: http://netikka.net/dev/black.exe OS/Version: Linux Status: UNCONFIRMED Severity: minor Priority: P2 Component: user32 AssignedTo: wine-bugs@winehq.org ReportedBy: ocean04@suomi24.fi
Small sample: http://netikka.net/dev/black.exe
2 comboboxes. First one is normal, second I have set doublebuffered := true;
Click arrow -> combobox turns black.
Actual problem is in larger component. It uses SetWindowPos to move it and draws icons. Problem is this black area is showing. Doublebuffering is set, component needs it.

--- Comment #3 from Nikolay Sivov bunglehead@gmail.com 2011-08-19 01:13:52 CDT --- It's not necessary user32 problem, there's no such thing as double buffer painting in user32, it's done entirely in Delphi component. That's why I always ask to use Lazarus for such simple test application, in case a problem is visible with it too so I can dig into its LCL sources.

If you need source, just google: controls.pas
Procedure is TWinControl.WMPaint
This line draws black:
BitBlt(DC, 0, 0, ClientRect.Right, ClientRect.Bottom, MemDC, 0, 0, SRCCOPY);
