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. https://github.com/iced-rs/iced/issues/816).

It might have to do with the absolute WIDTH/HEIGHT parameters (and the actual screen size?) that are set for binocle here: https://github.com/sharkdp/binocle/blob/db70c421c16fc528097559bea68a616b12a7906c/src/settings.rs#L3-L4

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

Thank you! I’m going to close this for now.

Works on macOS! 🚀

quackduck on Oct 17, 2021

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

awesome. thank you!

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

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

Done

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 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)

This also occurs on macOS 10.15.

Here is the full backtrace:

I also tried the head of branch db70c421c16fc528097559bea68a616b12a7906c and confirmed the same error building in both release and debug mode.
