[linux-audio-user] Fst + Crystal VST

Hello. There seems to be a persistant issue with Crystal VST and Fst. First, this appears at the launch of fst (with or without -r, with or without wineserver running) : cannot lock down memory for RT thread (Ne peut allouer de la memoire) The synth first seems to work perfectly, with audio and MIDI in jack. Then it quickly segfaults when using the GUI or just when playing some notes on vkeybd, at a moment or another, with this error message : The program 'fst' received an X Window System error. This probably reflects a bug in the program. The error was 'RenderBadPicture (invalid Picture parameter)'. (Details: serial 24972 error_code 191 request_code 156 minor_code 7) (Note to programmers: normally, X errors are reported asynchronously; that is, you will receive the error a while after causing it. To debug your program, run it with the --sync command line option to change this behavior. You can then get a meaningful backtrace from your debugger if you break on the gdk_x_error() function.) ² I have recompiled wine with or without gif, glut, opengl, gif, lcms, dbus and hal, and I have tried with or with DRI activated in xorg (free driver, ATI video card, dual monitor setup). Always the same. There is a recent bug report on the wine bugtracker here : http://bugs.winehq.org/show_bug.cgi?id=6673 and someone asked the same question sometime ago on this mailing list. But on the other hand there are many web sites where people report that this synth works perfectly with wine / fst. - Would someone have some kind of workaround ? - Would there be someone who uses Crstal vst sucessfully and could tell about his setup, especially his video card and drivers, xorg / xfree version, if he uses dual monitors and if DRI is activated ? - Did someone contact the author of Crystal to ask him about a native Linux version and / or a free version of his software's source code ? I could do it, but maybe there's a history about that I'm not aware of... Thanks for any advice or help, Y.
