Inside the antlr4 C++ runtime, antlr4-common.h includes `template using Ref = std::shared_ptr;` outside of any namespaces. This makes it difficult to integrate into existing C++ projects which already are `using...

Does not work in WKWebView

The check in https://github.com/xtermjs/xterm.js/blob/master/src/common/Platform.ts#L21: ``` export const isSafari = /^((?!chrome|android).)*safari/i.test(userAgent); ``` doesn't seem to catch [WKWebView](https://developer.apple.com/documentation/webkit/wkwebview?language=objc), which is the browser engine powering Safari. Safari's user agent string (on an iPad)...

Accessing an "invalid memory reference": Trapping behavior

17

## Background Today, regarding accessing "invalid memory references," [our spec says](https://gpuweb.github.io/gpuweb/wgsl/#invalid-memory-reference): > If a reference or pointer access is out of bounds, an invalid memory reference is produced. [Loads](https://gpuweb.github.io/gpuweb/wgsl/#load-rule) from...

Colorspace conversions for GPUExternalTexture are arbitrarily complex

[Migrated from #3288] Videos can embed arbitrary ICC profile information within themselves to describe the colorspace their texels are in. ICC profiles are not Turing-complete, but are [arbitrarily complex](https://color.org/specification/ICC.1-2022-05.pdf) -...

WGSL pointer aliasing rules

createPipelineAsync() doesn't reject its promise, even if the created pipeline is invalid

From https://gpuweb.github.io/gpuweb/#dom-gpudevice-createcomputepipelineasync: > When pipeline is ready to be used or has been made [invalid](https://gpuweb.github.io/gpuweb/#invalid), [resolve](https://webidl.spec.whatwg.org/#resolve) promise with pipeline. It seems like we should be rejecting the promise if the...

GPUBuffer.mapAsync is overly pessimistic
