| Subject: [PATCH] fixes: Prevent the cursor from leaking at corners |
| |
| This is a quick fix to prevent the cursor from leaking through between |
| xfixes boundaries at corners. Previously the barrier_is_blocking_direction |
| would consider e.g. a +X barrier to block -Y movement, so the second check |
| in CursorConstrainCursorHarder would repeat the same barrier in some |
| configurations. |
