           Summary: win16: garbled/corrupted window content (bad colors?)
           Product: Wine
           Version: 0.9.27.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-dos
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: xKiv at post.cz


(note: I *really* don't know where this bug belongs properly, the symptoms don't
connect with any single component .. and it is only in win16)

Bug found while using: blades of exile (available from
http://www.spiderwebsoftware.com/)

Since 0.9.20 [1] (and at least until 0.9.27), the win16 subsystem has a very
serious problem with, I assume, colors.
Pictures are worth a thousand words (big, screenshots):

(it was the same in all later versions that could actually run the program)
I seem to remeber this happening in some ancient versions of wine too.

There is an related issue that I will mention here, since it might have similar
cause (and is not worth fixing before fixing this bug):

In all versions of 0.9.x, where applicable (I managed to build wine, the program
was actually started and the 0.9.20-verybad issue was not yet present)
[this means: in 0.9.2-0.9.8, 0.9.10-0.9.14 and 0.9.16]:
some parts of the window content are black when first displayed, but are
corrected after re-exposure such as window movement (eighter the X window, or the
win16 window inside wine desktop), switching destops forth and back, clicking on
the area so that the application repaints it, ...).
Exhibits (full size gimp screenshots):
after startup: http://xKiv.matfyz.cz/wine-bugre/0.9.7-before.png
after clicking: http://xKiv.matfyz.cz/wine-bugre/0.9.7-after.png

As a sidenote, in 0.9.11, I noticed that the colors changed after futher
grabbing:

[1]: or maybe even before that, I couldn't fire my test case (running blades of
exile) in 0.9.15-0.9.19 because of unrelated bugs - unhandled page faults,
etc...)
