Hi all,

we have discovered a very ugly SRS-GNUstep related problem which causes the display not to be updated correctly, e.g. when popping up a combobox and scrolling through the items, or when scrolling through a text view or when clicking on items in a container view (actually NSView sublcasses on some other NSView subclass). "Display is not updated correctly" means that some stuff simply is not drawn.

This problem can't be Solaris related since it does not occur when I access the machine via Secure Global Desktop or directly on the console. It occurs only when using Sun Rays (Ultra Thin-Client from Sun Microsystems). I should normally ask Sun for help but then what should I tell them? The problem occurs only with GNUstep apps. The GNOME apps coming with the Sun Java Desktop work fine and do not show this effect even on Sun Rays. I doubt that Sun cares very much whether GUstep apps work together with their Sun Ray Server Software.

So what might cause this problem? Has anybody else seen this? I assume it's something in back...

This is really becoming a show stopper for us and we have no clue.

Any hints are greatly appreciated!

Thanks a lot in advance!

Regards,

  Andreas

Hi Andreas

We have a similar problem when we are using Mac OS X 10.4.x to host an XDM session (CDE) from a Sun Server running Solaris 8.  Our problem is with normal X11-Motif applications and is not replated at all to GNUstep.  Specifically, we do not see all of the button labels in menubar pulldown menus until we actually navigate through the menu items.  It is possible that this is the same problem.  Our apps display correctly when sent directly to the Mac OS X X-Server without the XDM CDE session.  We have not begun any type of investigation, so I can't give you any tips, other than to try and reproduce the problem that I'm describing and determine whether or not they are the same and if GNUstep is truly involved.  Please feel free to contact me directly if you have any other questions.

Best regards und Grüsse aus der Schweiz
