Issue

I and other users are experiencing segfaults when trying to run release builds of https://github.com/galister/wlx-overlay-s on AMD GPUs on Mesa 23.3.3 or Mesa 24.0.0.

Interestingly, it works fine with debug builds.

For Mesa 23.3.3 the segmentation fault occurs in vk_common_QueueSubmit (_queue=0x0, submitCount=1, pSubmits=0x7ffffafd5ce0, fence=0x0) at ../src/vulkan/runtime/vk_synchronization2.c:294 (mesa source) which shows that the queue handle is apparently 0x0.

After adding a simple debug message to wlx-overlay-s, we can confirm this difference in behavior between debug and release buids:

Debug:

[2024-02-10T23:10:14Z INFO  wlx_overlay_s::graphics] build_and_execute_now queue: Some(Queue { handle: 0x5555577e4f60, device: 0x5555578356f0 (instance: 0x555557779f40), flags: empty(), queue_family_index: 0, id: 0, state: Mutex { data: QueueState } })

Release with debug info:

[2024-02-10T23:12:07Z INFO  wlx_overlay_s::graphics] build_and_execute_now queue: Some(Queue { handle: 0x0, device: 0x55555656b4a0 (instance: 0x5555564af100), flags: empty(), queue_family_index: 0, id: 0, state: Mutex { data: QueueState } })
