[00:03:56] <symb0l> Yeah, you're probably right I'm trying to narrow down where the issue can be coming from and am having no luck.
[00:04:50] <baldurk> have you set VkDeviceQueueCreateInfo::pQueuePriorities incorrectly? i.e. uninitialised or not an array of queueCount values
[00:07:38] <symb0l> queueCount = 1; float priority = 1.0f; pQueuePriorities = &priority;
[00:15:46] <symb0l> https://pastebin.com/CfwUf60z snip of the function if it helps.
[00:16:41] <baldurk> you set enabledExtensionCount to 1 but don't set ppEnabledExtensionNames, so it's NULL
[00:18:34] <symb0l> Sorry, I tried removing that and it still faults
[00:21:27] <Ralith> make a debug build of the validation layers and run it in gdb
[00:21:30] <Ralith> should lead you right to the issue

[23:19:06] <mirv_> normally to invert a viewport, it's negative height, and then basically height for the y value, right?
[23:19:49] <mirv_> I do that and it's black screen instead of a flipped one, and I'm thinking I have to be missing something else

[23:55:10] <Ralith> I'm not sure what "negative height and then basically height" means
[23:56:03] <mirv_> viewport.height = -height
[23:56:07] <mirv_> viewport.y = height
[23:56:38] <Ralith> https://www.khronos.org/registry/vulkan/specs/1.1-extensions/man/html/VkViewport.html
[23:56:40] <baldurk> you've enabled the extension?
[23:56:45] <baldurk> (or enabled 1.1)
[23:56:59] <mirv_> I should be using 1.1
[23:57:02] <Ralith> maybe try setting y = 0?
[23:57:12] <mirv_> Ralith: tried that too, no change
[23:58:43] <baldurk> worth double checking to promote "should be" to "definitely am" since otherwise negative viewport height is invalid and might not work (depends on what the driver does)
[23:59:48] <mirv_> well, I'm definitely telling it to be 1.1, but looking now to make sure that's what is created
