Hi, I'm the original filer of that issue - I wasn't able to register before due to the anti-spam questions requiring very specific answers.
You shouldn't be using that force flag with Vulkan, and even if I do it's still not working correctly - the swapchain doesn't seem to be handling the display topology correctly. I bet it works for you on the internal laptop display, but have you tried running it on the internal laptop display while another external display is connected to either the iGPU or dGPU? If it works fine, can you show me your display topology using this tool:

I wouldn't mind stepping in and fixing this myself, do you happen to have some pointers as to where in the code should I be looking?
