           Summary: strange render window cutoff in both Party and Final
                    version
           Product: Wine
           Version: 0.9.34.
          Platform: PC
               URL: http://www.scene.org/file.php?file=/demos/groups/farb-
                    rausch/fr-030_candytron_final.zip&fileinfo
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: wine-directx-d3d
        AssignedTo: wine-bugs(a)winehq.org
        ReportedBy: mitch074(a)gmail.com


This is a 64k demo by Farb-rausch; that same group created several using the
same procedural content engine, and pretty much all of them function as intended
and don't exhibit that bug.
Essentially:
1-upon starting, the render window is correctly dimensioned as full screen (800x600)
2-after content generation bar reaches completion, 3D starts running in full
screen correctly
3-after the first screen blackout, the render window is truncated on the left
(+-20% of screen) and bottom (+- 30% of screen)

Playback goes well anyway; only minor defects such as overly strong HDR-like
effect and some missing fonts in the background (but only some - this may come
from a build defect, as other fonts appear)

Problem occurs in both GLSL and ARB modes (they seem identical otherwise). It
has been made for Geforce2-level hardware.

It once seemed to be very sensitive to sound emulation (required OSS driver
emulation), but now works with ALSA with 'standard' acceleration.

No error message in console when the bug occurs (only thing appearing is the
frame buffer size stub - making available RAM 128 Mb changes nothing) - as such
I guess it's not a missing function, but rather a bug in an existing function.
