Comment= # 8 on bug 97059<= /a> from Michel D=C3=A4nzer 
I suspect this is a blender bug. It clearly doesn't render at =
all to the
corrupted parts of its window, but AFAICT it doesn't use any of the
GLX_EXT_buffer_age, GLX_OML_swap_method or GLX_INTEL_swap_event extensions =
to
find out what if any guarantees there are about the contents of the back bu=
ffer
after a buffer swap. blender's assumptions about that may happen to be valid
with DRI2, which can only use up to two buffers, but not with DRI3, which c=
an
use more.
