X BadWindow error when attemtping to create a window with unsupported OpenGL attributes

[Bart van Strien]

When trying to create a window with unsupported OpenGL attributes, instead of failing gracefully (and then being able to try with a new set of attributes), an X error occurs instead, terminating the program. The error looks like this:

  X Error of failed request: BadWindow (invalid Window parameter)
    Major opcode of failed request: 4 (X_DestroyWindow)
    Resource id in failed request: 0x0
    Serial number of failed request: 154
    Current serial number in output stream: 156

This was a known bug in SDL2 that has been fixed in this commit: https://hg.libsdl.org/SDL/rev/2088cd828335

Only artful ships a package that is impacted by the bug, other ubuntu versions ship either an SDL2 version that is older, or a version that contains the fix. Would it be possible to backport the fix to the artful package?

A similar bug is still present in 2.0.10, but fixed in 2.0.12: https://hg.libsdl.org/SDL/rev/6e17e1a6cf2e
