Neothesia crashes at start

[DenpaBorisu]

Hello, I tried running Neothesia on my computer it crashes everytime, I even compiled it myself, it still crashes
The window decorations show for like half a second then it closes
I tried running the windows version on wine, it crashes at the start too

My system:
AMD Ryzen 5 2500U
Radeon Vega Mobile Gfx (8)
Ubuntu 20.04 with KDE on x11
Kernel: 5.12.0-051200-lowlatency
Mesa 21.1.0

The error message:

[2021-07-13T03:03:19Z INFO  neothesia::wgpu_jumpstart::gpu] Using AMD RADV RAVEN (ACO) (Vulkan, Prefered Format: Some(Bgra8UnormSrgb))
wgpu error: Validation Error

Caused by:

The error I get on wine running the Windows version:

55:err:vkd3d_load_vk_instance_procs: Could not get instance proc addr for 'vkGetPhysicalDeviceFragmentShadingRatesKHR'.

I dont know what additional info to submit or how to run neothesia with RUST_BACKTRACE=1 environment variable

Hi, thanks for detailed report, I have never seen this one before on my GPU.
Actually, Neothesia does not use set_scissor_rect anywhere, so it's probably a problem inherited from one of the libraries that I'm using.
Wine issue seems to be completely unrelated, for some reason it can't find a compatible GPU, and to be hones I don't care, I would rather fix native Linux build (although on my setup it does work in wine)

As I can't reproduce this in any way on my setup, wold you be willing to spend a little bit of time on trying to pinpoint the issue?

For example, my first suspects would be a font drawing library and UI library, so I would appreciate if you could test it's examples, and let me know if those work:
(like so)

git clone https://github.com/hecrj/iced.git
cd iced/examples/tour/ 
cargo run

After compilation is done It should look like this:

[DenpaBorisu]

Hello, thanks for the reply
I compiled the Iced tour thing, everything worked well, no error messages or any glitch

[PolyMeilex]

Ok, that's good, so It's probably in Neothesia.
Could you send your full Neothesia debug log?
You can enable it like so:
RUST_LOG=info RUST_BACKTRACE=1 cargo run

[DenpaBorisu]

Yes, here is the backtrace
neothesia backtrace.txt

[PolyMeilex]

I'm not sure what's causing the problem, but it originates from Iced, not sure why this problem does not manifest in tour example.
As a rule of thumb, I update iced to the newest version (it's available on Neothesia's master branch, you can check if that did anything)

From backtrace you gave me, I see that Neothesia fails as soon as it tries to draw its logo in main menu, so I temporarily disabled logo drawing in no-img branch, you can also check if that did anything.

Sorry for asking you for everything, but as I said I have no way to reproduce this, so I have to rely on your help

[DenpaBorisu]

I tested the no-img branch, it starts with no problems and everything seems to be working properly

[PolyMeilex]

That's great, thank you. I still don't know what's wrong, but at least you can run it. I'll try to find a cause, and if I stable upon something, I will let you know.

Not sure if a ought to create a new issue for this, so I'm adding my crash (on launch) details here.
