Couldn't find VkSurfaceKHR Object

[asafran]

Hello!
I get the following error when I try to run on kde neon (20.04) this example:

VUID-vkGetPhysicalDeviceSurfaceSupportKHR-surface-parameter(ERROR / SPEC): msgNum: -2145442690 - Validation Error: [ VUID-vkGetPhysicalDeviceSurfaceSupportKHR-surface-parameter ] Object 0: VK_NULL_HANDLE, type = VK_OBJECT_TYPE_INSTANCE; | MessageID = 0x801f247e | Invalid VkSurfaceKHR Object 0x555555f00560.

Thread 0, Frame 0:
vkGetPhysicalDeviceSurfaceSupportKHR(physicalDevice, queueFamilyIndex, surface, pSupported) returns VkResult

I try to build with Qt5.15.2 and Qt6.0.2. It looks like qt created an invalid surface. What Qt5 version are you using? Have you tried to run it on Linux?

I found a similar case on the qt forum: https://forum.qt.io/topic/123435/invalid-vksurface-from-qwidget
Is this a Qt bug?

Hello,

For the record, almost the same here on Win10 using Qt6.1.0 :

No, I currently have only a windows development computer.

Ok, I have to install Qt 6.x to test it. Currently I am using Qt 5.15.3.

Ok I have done further investigations on my side, so far just to keep you updated :

• I put teapot.vsgt in a models directory, taking it from vsgExamples/data/models (not present currently in the git of the projet do not know if related but just to be sure it's not related)
• I got logs indicating interactions with another FLOSS : OBS for broadcasting : "failed to start pipe" so uninstalled it to avoid interaction.

Now I manage to have a windows working and I'm able to Clear color ... via Customize, so the previous error is not showing up again. Got a new error when I try to reopen teapot.vsgt file via the Menu, will do further investigation on it.

Did anybody do anymore investigating into this? I'm having the same issue on Win10 with Qt 5.15.2:
