We are have similar problems with PF22 plus patches including 3229 on Irix 6.2
Machine Onyx IR, I pipe, Multichannel Option,
Performer apps and Vega apps based on Standard Performer window handling run OK.
but all apps that use a motif interface die every time in multi channel mode with the following
and sometimes in single channel mode????
Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 142 (GLX)
Minor opcode of failed request: 17 (X_GLXVendorPrivateWithReply)
Serial number of failed request: 172
Current serial number in output stream: 172
The program enters the main app loop having created the Motif managed window,
the graphics show and run for about 3 to 4 frames then just die with the above signal.
Problem being it exits without a core, and stepping through with CVD does not
seem to highlight any thing obvious apart from taking quite a while
The programs work fine with 6.2 on Max impacts, fine with 6.3 and o2's
and on Octanes.
Has any one found and wonder drugs for these type of frustrating symptoms
Regards
Gordon.
