Re^2: Plotting performance with cywin running under Win7

[Matthew Reich]

Marco,

Thank you very much for this suggestion.  It solved the grey window problem, which makes octave plots interactively presentable.

To pass the command line options to the Xserver:

    Change the command in the  Win 'Xwin Server' short cut icon, the target field, to
           C:\Cygwin\bin\run.exe /usr/bin/bash.exe -l -c  /usr/bin/startxwin-script

     Write a simple bash script in /usr/bin/startxwin-script that contains
            /usr/bin/startxwin.exe -- -multiwindow -nowgl


The script is needed, since in the context of C:\Cygwin\bin\run.exe, arguments to the bash.exe -c option do not seem to get passed.
So, for example, the following does not work:
        C:\Cygwin\bin\run.exe /usr/bin/bash.exe -l -c  /usr/bin/Xwin -multiwindow -nowgl


Thank you,
M.Reich

Matthew,
this bug seems due to WGL (windows integrated GL) interface
provided by Xwin

Try running the Xserver with "Xwin -multiwindow -nowgl"
it does not make the plot faster but at least the grey effect
does not appear when moving the plots.
