Hello guys,
I've run into a problem I can't seem able to solve. I've been testing and using both Ykhwong DAUM builds of the last past year and truth5678 DOSBOX-G modified version. They used to work flawlessly (and they still do). But the last two revisions from ykhwong (Nov. 17. 2013 - Jul. 25. 2013) give me a strange issue. Whenever I run directx-based or 3d accelerated games, the "active" windows seems to be comprehended inside a black cornice. I upload three pictures of the game Unreal to give you a valuable example. This wasn't happening with previous revisions. What is that? My drivers are up to date (I'm running Ati Radeon 6630M and Intel Core i5 2520).

Inside DAUM i'm running Windows 98 SE with glide=emu.

Dosbox.conf concerning SDL:

fullscreen=true
fulldouble=false
fullresolution=original
windowresolution=original
output=opengl
autolock=true
sensitivity=100
waitonerror=true
priority=higher,normal
mapperfile=mapper-SVN-Daum.map
pixelshader=none
usescancodes=false
overscan=0

Dosbox.conf concerning RENDER:

frameskip=0
aspect=true
linewise=false
char9=false
multiscan=false
scaler=none
autofit=true

Thanks for the constant diligence you put inside developing dosbox. I've been using DosBox for years since now, I've got my own personal Retro Rig containing a 3DFX Voodoo 5500 and I seldom use ykhwong DAUM builds to run Windows 98 inside Dosbox and achieve at the same time an amazing compatibility with older directx.
