Fullscreen on Windows+AMD is broken

[DeltaYelta]

There isn't a whole lot to say here tbh
I'm using the 0.19.0 release zip from github on windows 11 25H2

main.lua:

function lovr.draw(pass)
  pass:text('hello world', 0, 1.7, -3, .5)
end

conf.lua:

function lovr.conf(t)
  t.window.fullscreen = true
end

Running lovr.exe --console [folder with those files] opens the window saying 'hello world', which immediately freezes and stops responding after a moment. There's no output in the console, even with --graphics-debug. Disabling the headset module also doesn't change anything

Just tested it on 0.18.0 and it's probably worth pointing out that it works fine there

It's worth trying with --debug to see if there are any Vulkan errors (--graphics-debug was changed to --debug in v0.18.0).

Other info:

• Fullscreen changed in v0.19.0: Now t.window.fullscreen uses borderless fullscreen instead of exclusive fullscreen, and setting t.window.width and t.window.height to zero is deprecated.
• FWIW, I tested t.window.fullscreen on Linux/AMD/xwayland and it's working. So this may be specific to windows or certain GPUs.

oic; in that case the log is:

I installed the Vulkan SDK and used the default validation layer config, but the only difference was removing the message saying there isn't a validation layer installed.

So this may be specific to windows or certain GPUs.

My GPU is an AMD Radeon RX590 GME if that helps

I tested this on NV + Windows and AMD + Linux and couldn't reproduce it, so it seems specific to Windows/AMD. Might be worth making sure the drivers were up to date too.

[DeltaYelta]

alright, I tried it on WSL and it works fine there. According to my AMD software, my drivers are up to date as well.

[DeltaYelta]

on my laptop with Intel integrated graphics, it also works just fine

Tried it on Windows + AMD 8060S, also works
