rawrscope's Issues

Panic on launch: "assertion failed: `(left == right)`"

When I try to run cargo run --release, a blank rawrscope windows, followed by a panic in the terminal:

Running in the vscode CodeLLDB debugger implicates wgpu and DX12.

Specifically, this line in rawrscope crashes:

rawrscope/src/render.rs

Lines 104 to 114 in b86f3f5

	let line_ssbo_bind = device.create_bind_group(&wgpu::BindGroupDescriptor {
	layout: &line_ssbo_bind_layout,
	bindings: &[wgpu::Binding {
	binding: 0,
	resource: wgpu::BindingResource::Buffer {
	buffer: &line_ssbo,
	range: 0..1,
	},
	}],
	label: Some("scope line ssbo bind group"),
	});

And this line in wgpu:

https://github.com/gfx-rs/wgpu/blob/bc065e4abc24e82a2c92403740ffe8d7e6643243/wgpu-core/src/device/mod.rs#L1219

Which calls function https://github.com/gfx-rs/gfx/blob/fdfe887f5afab7ca057e3e824817d0bcdcf794ba/src/backend/dx12/src/device.rs#L2816 (but with no debug symbols)

I'll report an upstream bug soon.

OS compatibility

Report issues with compiling or running on any supported operating systems (Windows, macOS, Linux) here

[WIN10] Undefined Error

Tried to test out rawrscope today, but trying to run the executable gives this:
Image Of Error

"rawrscope encountered an unrecoverable error. no additional information."

Actually fix presentation logic

(Extension of #7)

Right now it's very scuffed, relying on a weird timer system. The new/final system should:

• Continue using a timer to redraw the scope preview
• Not use ControlFlow::Poll
• Use Event::RedrawRequested
• Use ControlFlow::WaitUntil during playback to redraw when scopes update
• Triple-buffer final frames (requires upstream implementation)

Stuttering / tearing with new presentation logic

a4bccbd introduces a new issue where the uncapped framerate may not be in sync with the target framerate, which will often be 60fps and match the user's display. On Windows and certain Linux desktops where there is VSync over everything, this results in stutters in the preview. On macOS this results in tearing. The tearing could be fixed by implementing triple-buffering upstream in wgpu, but that would just make the stuttering consistent across every platform. I think that may have to be the only solution though since there doesn't seem to be a single way to query when a frame has truly been presented when triple-buffering.

Throttle master audio submission

Right now the master audio "buffer" can build up endlessly, resulting in massive audio desync if the submissions from the main thread are too large. Ideally, submission should block if there is too much audio data queued up, but I'm not sure how to implement that yet.

Investigate line antialiasing

Right now I'm pretty sure the antialiasing algorithm used for line rendering is just an approximation; it would be nice to compute the exact value based on the trapezoidal coverage of the pixel. I'm almost certain it's possible, but i looked at it a while ago and wasn't able to work through the math. I doubt there would really be much of a noticeable difference, so this would probably be an opt-in feature.

Lag when dragging UI elements around in debug builds

Git: master b3316d7
OS: Windows 10 x64

When I run a debug build of rawrscope, then drag a UI element (nested subwindow), it lags behind the cursor. The longer I keep dragging, the further the subwindow falls behind. During the process, rawrscope only eats around half a core of CPU (due to GPU sync?) and other UI elements don't respond. This does not occur in release mode.

Is this an imgui issue? Does it occur on slower computers or just in debug mode? Not sure how relevant this is.

Solution: choco install ninja.

There might be other undocumented dependencies I have installed so didn't catch. No clue.

Write tests

Should cover most of the codebase, no idea what the target % should be.

1 frame lag in UI with VSync enabled

This may be resolvable, but it might also just be a fundamental flaw in imgui. Need more research or someone else's input. VSync is required for audio sync.

Clean up dependencies

There are currently a lot of unnecessary (convenience) dependencies that are inflating build times and likely executable size too.

Line rendering without geometry shaders?

Some old hardware may not support geometry shaders, which are currently required for line rendering. It is possible to implement it without geometry shaders, however it is at the expense of generating more verts on the CPU and using a bit more memory bandwidth every frame. It may not even be worth it to support devices this old, especially depending on what the overall performance cost will be.
