Subject: [PATCH] drisw: Do not use drisw_put_image_shm
The put_image_shm is temporarily disabled to workaround crashes in
applications that create two software-rendering OpenGL contexts, each
time using different version of loader. This caused crashes because the
drisw_lf variable is shared between them.
