This also occurs on macOS 10.15.

I also tried the head of branch db70c42 and confirmed the same error building in both release and debug mode.

Thank you for reporting this. I don't have a (native) Windows or MacOS system to test. I kind of just hoped that the binaries would work.

Any help would be very much appreciated.

The error seems to originate from wgpu (https://github.com/gfx-rs/wgpu/blob/76bcd9c494a4359853bc2caec8eebbaa990a34e3/wgpu-core/src/command/draw.rs#L92-L93, https://github.com/gfx-rs/wgpu/blob/76bcd9c494a4359853bc2caec8eebbaa990a34e3/wgpu-core/src/command/render.rs#L1221-L1227). There are a few (possibly) related issues on GitHub (e.g. iced-rs/iced#816).

It might have to do with the absolute WIDTH/HEIGHT parameters (and the actual screen size?) that are set for binocle here:

binocle/src/settings.rs

Lines 3 to 4 in db70c42

	pub const WIDTH: u32 = 1366;
	pub const HEIGHT: u32 = 1024;

Maybe someone could test setting them to other (lower?) values like 800x600?

I tried it, but still get the same error.

[rhysd]

set_scissor_rect is only called here in egui_wgpu_backend crate.

https://github.com/hasenbanck/egui_wgpu_backend/blob/74f63a071ff6578688f18d8091bf549d417b2c8f/src/lib.rs#L335

[simonsan]

I checked it on my Debian 11 system and it throws the same error.

[tan-wei]

Met the same issue on MacOS and Windows.

Any updates on this? Which operating system and general setup is it being tested on and successfully working? @sharkdp

[sharkdp]

No updates from me. As I said, I would need help from someone with MacOS/Windows and preferably some knowledge of wgpu.

It's working fine for me on (Arch) Linux, x86.

Hmm ok, as far as I'm concerned it's not working on Debian Linux x86_64 , though :/ I haven't found a system it's working on tbh. :(

Oh :-/. It's working on Ubuntu 20.04 for me as well.

Could someone please try to run this minimal example here: https://github.com/parasyte/pixels/tree/master/examples/egui-winit? This is what binocle is based on. This should allow us to see if I did something wrong in this project. Or if it's a more fundamental issue.

It works for me. (Tested on Win10 19043)

[sharkdp]

I updated the dependencies for binocle. Could someone please build from master and try again? If that doesn't work, I can also provide binaries.

Compiled from master, same error.

[sharkdp]

Thank you.

I tried to run binocle in a Debian docker container and it worked fine after installing vulkan graphics libraries. Before that, it didn't work at all (No suitable wgpu::Adapter found), but I could not reproduce the error.

To further debug this, it might be helpful to set a few environment variables:

export RUST_BACKTRACE=1
export RUST_LOG=trace

Could you try to run it with these variables set?

It might also help to request another GPU (if you have an integrated GPU and a dedicated graphics card, for example):

WGPU_POWER_PREF=high

[sharkdp]

I also found another weird thing which I just fixed on master. It might be worth to update to the latest commit and try again.

[sharkdp]

I released a new version if someone else wants to give this a try: https://github.com/sharkdp/binocle/releases/tag/v0.1.2

[simonsan]

I released a new version if someone else wants to give this a try: https://github.com/sharkdp/binocle/releases/tag/v0.1.2

Tried it with an uploaded binary from the releases on Windows (x68_64) and now it works.

Could you publish on crates.io please, as well?

Could someone on MacOS verify if this fixes the problem as well?

Could you publish on crates.io please, as well?
