We think we've fixed all the related bugs in the kernel, so you can try flipping the switch and see what happens. However, I think your symptoms are only a side-effect of disabling relaxed fencing. The cause is actually more likely to be the use of an untiled buffer for an image with a stride of greater then 4096 bytes. With relaxed fencing there is less likelihood of any such buffers being present and so reused for textures. -Chris -- Chris Wilson, Intel Open Source Technology Centre _______________________________________________ Intel-gfx mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/intel-gfx
