Hate to say this, but not a blender bug. It's a rather old bug in Mesa which is being ignored by Mesa developers: https://bugs.freedesktop.org/show_bug.cgi?id=59455

Workaround would be to use blender-softwaregl from official build archive.

Thanks for the report, but we can not fix bugs in video drivers.
