Simplified alternative to fix in #18 and commented a bit what's happening on a frame drop (took me way too long to figure that out again). I decided to ignore the
BufferAsyncError
after all in the expectation that wgpu will soon be able to report aborted mappings. This should be safe since the only way to trigger this error is anunmap
call (and naturally, wgpu-profile owns all of these for the buffers in question), see https://www.w3.org/TR/webgpu/#dom-gpubuffer-unmapHowever, the error code are not yet exposed in wgpu, eagerly awaiting the resolution gfx-rs/wgpu#2939
PR comes with a regression test :)
(which gives a stable repro for the previous issue)
