          Priority: medium
            Bug ID: 58100
          Assignee: mesa-dev at lists.freedesktop.org
           Summary: Mesa generates BadMatch error when making context
                    current with no drawable
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: alanh at fairlite.co.uk
          Hardware: Other
            Status: NEW
           Version: git
         Component: Mesa core
           Product: Mesa

With the advent of GLX_ARB_create_context(_profile) the specification allows a
context to be bound without a read/write drawable when the OpenGL version
requested is 3.0 or higher.

Unfortunately the GLX code, and potientially other side effects won't allow
this as MakeContextCurrent() will generate a BadMatch error when binding a
context to NULL drawables.
