wine users - Jun 2010 - Poor performance while drawing text input fields and buttons

Poor performance while drawing text input fields and buttons with GDI commands
using winex11.drv

Hello,
   I have noticed that an application compiled under wnidows that makes
extensive use of GDI
drawing commands, even when it is run in the latest 1.2rc3 vesion of wine, shows
a slow down
while drawing a window with a lot of buttons and text input fields.

I have tried to do verbose debug of the application with the
command"WINEDEBUG=+relay wine App.exe"
and the result was that I saw a huge amount of ntdll.RtlEnterCriticalSection()
and
ntdll.RtlLeaveCriticalSection(). These calls were made while drawing the
graphical elements, so I
have commented out the following rows in the file winex11.drv/x11drv_main.c:

void CDECL wine_tsx11_lock(void)
{
  // EnterCriticalSection( &X11DRV_CritSection );
}

void CDECL wine_tsx11_unlock(void)
{
   // LeaveCriticalSection( &X11DRV_CritSection );
}


After this I have compiled and installed wine 1.2rc3 and I am going to test the
drawing
performance of App.exe with this modified version of wine. Is this a good
solution or maybe there
are other solutions that I should try in order to speed-up the drawing of
buttons and text input
fields with winex11.drv?

Thanks in advance,

I think this is the same problem that is happening with me.

My windows app makes use of wingdi wich is the same that is causing troubles
with you.

Well,

actually the removal of enter/leave for the critical sections was not of any
use... I achieved no speedup.

The drawing of the buttons and of the text input field seems to be slow because
of the following calls:

0009:Call gdi32.SetBkColor(00000250,00c8d0d4) ret=004327f3
0009:Ret  gdi32.SetBkColor() retval=00ffffff ret=004327f3
0009:Call gdi32.SetTextColor(00000250,00000000) ret=004327d9
0009:Ret  gdi32.SetTextColor() retval=00000000 ret=004327d9
0009:Call gdi32.SetBkColor(00000250,00ffffff) ret=004327f3
0009:Ret  gdi32.SetBkColor() retval=00ffffff ret=004327f3
0009:Call gdi32.SetTextColor(00000250,00000000) ret=004327d9
0009:Ret  gdi32.SetTextColor() retval=00000000 ret=004327d9
0009:Call gdi32.SetBkColor(00000250,00ffffff) ret=004327f3
0009:Ret  gdi32.SetBkColor() retval=00ffffff ret=004327f3

Is it possible to reduce in any way the time that each of these spend?

Thanks,

Well, actually the problem was in the file dlls/winex11.drv/bitblt.c in the
function


Code:
/***********************************************************************
 *           X11DRV_StretchBlt
 */
BOOL CDECL X11DRV_StretchBlt( X11DRV_PDEVICE *physDevDst, INT xDst, INT yDst,
INT widthDst, INT heightDst,
                              X11DRV_PDEVICE *physDevSrc, INT xSrc, INT ySrc,
INT widthSrc, INT heightSrc,
                              DWORD rop )



because after issuing the command 
> WINEDEBUG=+bitblt wine ./App.exe
there were a lot of 

trace:bitblt:X11DRV_StretchBlt     rectdst=25,1 1x13 orgdst=10,10
visdst=(25,1)-(26,14)
trace:bitblt:X11DRV_StretchBlt     rectsrc=0,0 1x13 orgsrc=0,0
vissrc=(0,0)-(1,13)
trace:bitblt:BitBlt hdcSrc=0x3ed0 0,0 -> hdcDest=0x1ec8 25,1 1x13 rop=660046
trace:bitblt:X11DRV_StretchBlt     rectdst=25,1 1x13 orgdst=10,10
visdst=(25,1)-(26,14)
trace:bitblt:X11DRV_StretchBlt     rectsrc=0,0 1x13 orgsrc=0,0
vissrc=(0,0)-(1,13)

that were synchronized with the slow display of the buttons and text input
fields.

Can anyone provivde me an optimized version of this function?
Thanks very much
