I have a bug related to the vulkan compute. In the compute shader, if set local size something like:
layout (local_size_x = 32, local_size_y = 32, local_size_z = 1) in;
The compute app works ok. But if set local_size_z greater than 1:
layout (local_size_x = 32, local_size_y = 32, local_size_z = 2) in;
The compute app freezes after the command buffer has been dispached (Linux Debian sid 4.18.10-2).
The situation on Windows is slightly different. If local_size_z greater than 1, the compute app does not freezes, but computational result is incorrect(all output buffer values are zero).
The Validation layer(VK_LAYER_LUNARG_standard_validation) was enabled on both OS (Linux and Windows).
Nvidia Geforce 1070ti

This is simple compute app, that copy values from one buffer to another.
