#61959: Issue with XQuartz & legacy X forwarding
--------------------+-------------------------

--------------------+-------------------------
 The team over at sgi.sh have been trying to get X11 forwarding working on
 SGI IRIX > MacOS for a while without luck. First was the iglx issue which
 we worked out, but secondly there seems to be an issue with Xinerama and
 its interaction with XQuartz. After doing research into this issue, it
 seems to have been a consistent bug for almost 15 years (I will provide
 references at the end)
 {{{
 X Error of failed request: BadWindow (invalid Window parameter) Major
 opcode of failed request: 128 (XINERAMA) Minor opcode of failed request: 1
 (XINERAMAGetState) Resource id in failed request: 0xa9010000 Serial number
 of failed request: 760 Current serial number in output stream: 760
 }}}
 This error presents when running 'certain' applications over Xforwarding,
 notably ones with more complex GLX requirements, like the window manager
 in Irix that uses vector icons etc. It doesn't seem to be related to
 indirect rendering, but it does require indirect rendering to be working
 correctly. We currently have Mac users forced to run Linux VM's on their
 glorious MacOS in order to use Xforwarding... the horror! :)

 I hope this is something the team here might be able to look in to? I do
 appreciate it may not be specific to Macports but any kind of help is
 appreciated. Thanks.
