Bug ID: 55927
           Summary: RestoreDC appears to fail with printers
           Product: Wine
           Version: 8.19
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

My wine is packed within the OpenSuse Tumbleweed distribution. Since recently,
I experience problems with printing from a custom application which worked in
earlier wine versions. Its graphical output (mostly data represented as lines
and text) is normally shown on the screen where I encounter no problems.
However, currently, when the data is sent to a printer - either one with paper
or the CUPS pdf printer -, it is clipped to a rectangle defined by the SaveDC
function. This would be OK except that the function RestoreDC

BOOL RestoreDC
(
  [in] HDC hdc,
  [in]
int
 nSavedDC
)
;

does not work properly with the device context hdc connected to a printer
device.

In brief, the sequence

SaveDC

(functions involving clipping of the output region)

RestoreDC

does not restore the clipping region to the original one for the printer
(however, it does for the screen device context).
