Subject: xlib/shm: Force synchronisation for scratch SHM image buffers
|
| 5 |
|
| 6 |
The scratch image buffers are used for uploads to the xserver and so we
|
| 7 |
must be careful not to overwrite active SHM segments. Unfortunately we
|
| 8 |
told the core SHM allocator that we would sync before using the images,
|
| 9 |
which was a lie.
