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.
